USB Interface

OTG Interface

EZ-OTG has two built-in Host/Peripheral SIEs that each have

a single USB transceiver, meeting the USB 2.0 specification

requirements for full and low speed (high speed is not support-

ed). In Host mode, EZ-OTG supports two downstream ports;

each supports control, interrupt, bulk, and isochronous trans-

fers. In Peripheral mode, EZ-OTG supports one peripheral

port with eight endpoints for each of the two SIEs. Endpoint 0

is dedicated as the control endpoint and only supports control

transfers. Endpoints 1 though 7 support Interrupt, bulk (up to

64 bytes per packet), or isochronous transfers (up to 1023

bytes per packet size). EZ-OTG also supports a combination

of Host and Peripheral ports simultaneously, as shown in

T a ble 2.

EZ-OTG has one USB port that is compatible with the USB

On-The-Go supplement to the USB 2.0 specification. The USB

OTG port has various hardware features to support Session

Request Protocol (SRP) and Host Negotiation Protocol (HNP).

OTG is only supported on USB PORT 1A.

OTG Features

• Internal Charge Pump to supply and control VBUS

• VBUS Valid Status (above 4.4V)

• VBUS Status for 2.4V < VBUS < 0.8V

• ID Pin Status

• Switchable 2-Kohm internal discharge resistor on VBUS

• Switchable 500-ohm internal pull-up resistor on VBUS

Host Port Interface (HPI)

Table 9. HPI Interface Pins

(continued)

EZ-OTG has an HPI interface. The HPI interface provides

DMA access to the EZ-OTG internal memory by an external

host, plus a bidirectional mailbox register for supporting

high-level communication protocols. This port is designed to

be the primary high-speed connection to a host processor.

Complete control of EZ-OTG can be accomplished through

this interface via an extensible API and communication

protocol. Other than the hardware communication protocols, a

host processor has identical control over EZ-Host whether

connecting to the HPI or HSS port. The HPI interface is

exposed through GPIO pins.

Note It should be noted that for up to 3 ms after BIOS starts

executing, GPIO[24:19] and GPIO[15:8] will be driven as

outputs for a test mode. If these pins need to be used as inputs,

a series resistor is required (10 ohm to 48 ohm is recom-

mended). Refer to BIOS documentation for addition details.

See section “Reset Pin” on page 9.

The two HPI address pins are used to address one of four

possible HPI port registers as shown in T a ble 10 below.

Operational Modes

There are two modes of operation: Coprocessor and

Standalone.

Table 13.Crystal Pins

Coprocessor Mode

EZ-OTG can act as a coprocessor to an external host

processor. In this mode, an external host processor drives

EZ-OTG and is the main processor rather then EZ-OTG’s own

16-bit internal CPU. An external host processor may interface

to EZ-OTG through one of the following three interfaces in

coprocessor mode:

XTALOUT

Boot Configuration Interface

EZ-OTG can boot into any one of four modes. The mode it

boots into is determined by the TTL voltage level of

GPIO[31:30] at the time nRESET is deasserted. T a ble 14

shows the different boot pin combinations possible. After a

reset pin event occurs, the BIOS bootup procedure executes

for up to 3 ms. GPIO[31:30] are sampled by the BIOS during

bootup only. After bootup these pins are available to the appli-

cation as GPIOs.

• HPI mode, a 16-bit parallel interface with up to 16 MBytes

transfer rate

• HSS mode, a serial interface with up to 2M baud transfer

rate

• SPI mode, a serial interface with up to 2 Mbits/s transfer

rate.

Table 14.Boot Configuration Interface

At bootup GPIO[31:30] determine which of these three inter-

faces are used for coprocessor mode. Refer to T a ble 14 for

details. Bootloading begins from the selected interface after

POR + 3 ms of BIOS bootup.

Standalone Mode

Serial Peripheral Interface (SPI, slave

In standalone mode, there is no external processor connected

to EZ-OTG. Instead, EZ-OTG’s own internal 16-bit CPU is the

main processor and firmware is typically downloaded from an

EEPROM. Optionally, firmware may also be downloaded via

USB. Refer to T a ble 14 for booting into standalone mode.

I2C EEPROM (Standalone Mode)

GPIO[31:30] must be pulled high or low, as needed, using

resistors tied to V or GND with resistor values between 5K

ohm and 15K ohm. GPIO[31:30] must not be tied directly to

those two pins are used for the serial I2C EEPROM (if imple-

mented). The resistors used for these pull ups must conform

to the serial EEPROM manufacturer's requirements.

• GPIO[28:27] are enabled for debug UART mode.

• GPIO[29] is configured as OTGID for OTG applications on

PORT1A.

If any mode other then standalone is chosen, EZ-OTG will be

in coprocessor mode. The device will power up with the appro-

priate communication interface enabled according to its boot

pins and wait idle until a coprocessor communicates with it.

See the BIOS documentation for greater detail on the boot

process.

— If OTGID is logic 1 then PORT1A (OTG) is configured

as a USB peripheral.

— If OTGID is logic 0 then PORT1A (OTG) is configured

as a USB host.

• Ports 1B, 2A, and 2B default as USB peripheral ports.

• All other pins remain INPUT pins.

Power Savings and Reset Description

Sleep mode is the main chip power down mode and is also

used for USB suspend. Sleep mode is entered by setting the

Sleep Enable (bit 1) of the Power Control register [0xC00A].

During Sleep mode (USB Suspend) the following events and

states are true:

The EZ-OTG modes and reset conditions are described in this

section.

Power Savings Mode Description

EZ-OTG has one main power savings mode, Sleep. For

detailed information on Sleep mode; See section “Sleep”.

• GPIO pins maintain their configuration during sleep (in

suspend).

Sleep mode is used for USB applications to support USB

suspend and non USB applications as the main chip power

down mode.

• External Memory Address pins are driven low.

• XTALOUT is turned off.

• Internal PLL is turned off.

In addition, EZ-OTG is capable of slowing down the CPU clock

speed through the CPU Speed register [0xC008] without

affecting other peripheral timing. Reducing the CPU clock

speed from 48 MHz to 24 MHz reduces the overall current

draw by around 8 mA while reducing it from 48 MHz to 3 MHz

reduces the overall current draw by approximately 15 mA.

• Firmware must disable the charge pump (OTG Control

Otherwise OTGVBUS will only drop to V – (2 schottky

diode drops).

• Booster circuit is turned off.

• USB transceivers is turned off.

• CPU suspends until a programmable wakeup event.

control registers from 0xC000 to 0xC0FF and the BIOS ROM

itself from 0xE000 to 0xFFFF. For more information on the

reserved lower memory or the BIOS ROM, refer to the

There are several possible events available to wake EZ-OTG

from Sleep mode as shown in T a ble 15. These may also be

used as remote wakeup options for USB applications. See

section “Power Control Register [0xC00A] [R/W]” on page 13.

Upon wakeup, code begins executing within 200 ms, the time

it takes the PLL to stabilize.

During development with the EZ-OTG toolset, the lower area

of User's space (0x04A4 to 0x1000) should be left available to

load the GDB stub. The GDB stub is required to allow the

SPI Wake Enable (Bit 8)

The Power Control register controls the power-down and

wakeup options. Either the sleep mode or the halt mode

options can be selected. All other writable bits in this register

can be used as a wakeup source while in sleep mode.

The SPI Wake Enable bit enables or disables a wakeup

condition to occur on a falling SPI_nSS input transition. The

processor may take several hundreds of microseconds before

being operational after wakeup. Therefore, the incoming data

byte that causes the wakeup will be discarded.

Host/Device 2 Wake Enable (Bit 14)

1: Enable wakeup on falling SPI nSS input transition

0: Disable SPI_nSS interrupt

The Host/Device 2 Wake Enable bit enables or disables a

wakeup condition to occur on an Host/Device 2 transition. This

wake up from the SIE port does not cause an interrupt to the

on-chip CPU.

HPI Wake Enable (Bit 7)

The HPI Wake Enable bit enables or disables a wakeup

condition to occur on an HPI interface read.

1: Enable wakeup on Host/Device 2 transition.

0: Disable wakeup on Host/Device 2 transition.

1: Enable wakeup on HPI interface read

0: Disable wakeup on HPI interface read

Host/Device 1 Wake Enable (Bit 12)

The Host/Device 1 Wake Enable bit enables or disables a

wakeup condition to occur on an Host/Device 1 transition. This

wakeup from the SIE port does not cause an interrupt to the

on-chip CPU.

GPI Wake Enable (Bit 4)

The GPI Wake Enable bit enables or disables a wakeup

condition to occur on a GPIO(25:24) transition.

1: Enable wakeup on Host/Device 1 transition

0: Disable wakeup on Host/Device 1 transition

1: Enable wakeup on GPIO(25:24) transition

0: Disable wakeup on GPIO(25:24) transition

Boost 3V OK (Bit 2)

OTG Wake Enable (Bit 11)

The Boost 3V OK bit is a read only bit that returns the status

of the OTG Boost circuit.

The OTG Wake Enable bit enables or disables a wakeup

condition to occur on either an OTG VBUS_Valid or OTG ID

transition (IRQ20).

1: Boost circuit not ok and internal voltage rails are below 3.0V

1: Enable wakeup on OTG VBUS valid or OTG ID transition

0: Disable wakeup on OTG VBUS valid or OTG ID transition

0: Boost circuit ok and internal voltage rails are at or above

3.0V

Sleep Enable (Bit 1)

HSS Wake Enable (Bit 9)

Setting this bit to ‘1’ immediately initiates SLEEP mode. While

in SLEEP mode, the entire chip is paused achieving the lowest

standby power state. All operations are paused, the internal

clock is stopped, the booster circuit and OTG VBUS charge

pump are all powered down, and the USB transceivers are

powered down. All counters and timers are paused but will

retain their values. SLEEP mode exits by any activity selected

in this register. When SLEEP mode ends, instruction

execution resumes within 0.5 ms.

The HSS Wake Enable bit enables or disables a wakeup

condition to occur on an HSS Rx serial input transition. The

processor may take several hundreds of microseconds before

being operational after wakeup. Therefore, the incoming data

byte that causes the wakeup will be discarded.

1: Enable wakeup on HSS Rx serial input transition

ACK Flag (Bit 0)

1: For non-Isochronous transfers, the transaction was ACKed.

For Isochronous transfers, the transaction was completed

successfully.

The ACK Flag bit indicates two different conditions depending

on the transfer type. For non-Isochronous transfers, this bit

represents a transaction ending by receiving or sending an

ACK packet. For Isochronous transfers, this bit represents a

successful transaction that will not be represented by an ACK

packet.

0: For non-Isochronous transfers, the transaction was not

ACKed. For Isochronous transfers, the transaction was not

completed successfully.

NAK Interrupt Enable (Bit 3)

The Device n Endpoint n Control register provides control over

a single EP in device mode. There are a total of eight

endpoints for each of the two ports. All endpoints have the

same definition for their Device n Endpoint n Control register.

The NAK Interrupt Enable bit enables and disables the gener-

ation of an Endpoint n interrupt when the device responds to

the host with a NAK. The Endpoint n Interrupt Enable bit in the

Device n Interrupt Enable register must also be set. When a

NAK is sent to the host, the corresponding EP Interrupt Flag

in the Device n Status register will be set. In addition, the NAK

Flag in the Device n Endpoint n Status register will be set.

IN/OUT Ignore Enable (Bit 6)

The IN/OUT Ignore Enable bit forces endpoint 0 (EP0) to

ignore all IN and OUT requests. This bit must be set so that

EP0 only excepts Setup packets at the start of each transfer.

This bit must be cleared to except IN/OUT transactions. This

bit only applies to EP0.

1: Enable NAK interrupt

0: Disable NAK interrupt

Direction Select (Bit 2)

1: Ignore IN/OUT requests

The Direction Select bit needs to be set according to the

expected direction of the next data stage in the next trans-

action. If the data stage direction is different from what is set

in this bit, it will get NAKed and either the IN Exception Flag or

the OUT Exception Flag will be set in the Device n Endpoint n

Status register. If a setup packet is received and the Direction

Select bit is set incorrectly, the setup will be ACKed and the

Set-up Status Flag will be set (refer to the setup bit of the

Device n Endpoint n Status register for details).

0: Do not ignore IN/OUT requests

Sequence Select (Bit 6)

The Sequence Select bit determines whether a DATA0 or a

DATA1 will be sent for the next data toggle. This bit has no

effect on receiving data packets, sequence checking must be

handled in firmware.

1: Send a DATA1

0: Send a DATA0

1: OUT transfer (host to device)

0: IN transfer (device to host)

Stall Enable (Bit 5)

Enable (Bit 1)

The Stall Enable bit sends a Stall in response to the next

request (unless it is a setup request, which are always

ACKed). This is a sticky bit and continues to respond with

Stalls until cleared by firmware.

The Enable bit must be set to allow transfers to the endpoint.

If Enable is set to ‘0’ then all USB traffic to this endpoint is

ignored. If Enable is set ‘1’ and Arm Enable (bit 0) is set ‘0’ then

NAKs will automatically be returned from this endpoint (except

setup packets, which are always ACKed as long as the Enable

bit is set).

1: Send Stall

0: Do not send Stall

1: Enable transfers to an endpoint

ISO Enable (Bit 4)

0: Do not allow transfers to an endpoint

The ISO Enable bit enables and disables an Isochronous

transaction. This bit is only valid for EPs 1–7 and has no

function for EP0.

Arm Enable (Bit 0)

The Arm Enable bit arms the endpoint to transfer or receive a

packet. This bit is cleared to ‘0’ when a transaction is complete.

Underflow Flag (Bit 10)

The Device n Endpoint n Status register provides packet status

information for the last transaction received or transmitted.

This register is updated in hardware and does not need to be

cleared by firmware. There are a total of eight endpoints for

each of the two ports. All endpoints have the same definition

for their Device n Endpoint n Status register.

The Underflow Flag bit indicates that the received data in the

last data transaction was less then the maximum length

specified in the Device n Endpoint n Count register. The

Underflow Flag should be checked in response to a Length

Exception signified by the Length Exception Flag set to ‘1’.

an IN packet when armed for an OUT.

0: Setup packet was not received

Sequence Flag (Bit 3)

1: Received IN when armed for OUT

0: Received OUT when armed for OUT

The Sequence Flag bit indicates whether the last data toggle

received was a DATA1 or a DATA0. This bit has no effect on

receiving data packets; sequence checking must be handled

The Stall Flag bit indicates that a Stall packet was sent to the

host.

1: DATA1 was received

0: DATA0 was received

1: Stall packet was sent to the host

0: Stall packet was not sent

Timeout Flag (Bit 2)

The Timeout Flag bit indicates whether a timeout condition

occurred on the last transaction. On the device side, a timeout

can occur if the device sends a data packet in response to an

IN request but then does not receive a handshake packet in a

predetermined time. It can also occur if the device does not

receive the data stage of an OUT transfer in time.

NAK Flag (Bit 6)

The NAK Flag bit indicates that a NAK packet was sent to the

host.

1: NAK packet was sent to the host

0: NAK packet was not sent

1: Timeout occurred

Length Exception Flag (Bit 5)

0: Timeout condition did not occur

The Length Exception Flag bit indicates the received data in

the data stage of the last transaction does not equal the

maximum Endpoint Count specified in the Device n Endpoint

n Count register. A Length Exception can either mean an

overflow or underflow and the Overflow and Underflow flags

(bits 11 and 10, respectively) should be checked to determine

which event occurred.

Result (Bits [15:0])

The Device n Endpoint n Count Result register contains the

size difference in bytes between the Endpoint Count specified

in the Device n Endpoint n Count register and the last packet

received. If an overflow or underflow condition occurs, that is

the received packet length differs from the value specified in

the Device n Endpoint n Count register, the Length Exception

Flag bit in the Device n Endpoint n Status register will be set.

The value in this register is only considered when the Length

Exception Flag bit is set and the Error Flag bit is not set; both

bits are in the Device n Endpoint n Status register.

The Result field contains the differences in bytes between the

received packet and the value specified in the Device n

Endpoint n Count register. If an overflow condition occurs,

Result [15:10] is set to ‘111111’, a 2’s complement value

indicating the additional byte count of the received packet. If

an underflow condition occurs, Result [15:0] indicates the

excess byte count (number of bytes not used).

Reserved

All reserved bits must be written as ‘0’.

The Device n Endpoint n Count Result register is a memory

based register that must be initialized to 0x0000 before USB

Device operations are initiated. After initialization, this register

must not be written to again.

The HPI Breakpoint register is a special on-chip memory location, which the external processor can access using normal HPI

memory read/write cycles. This register is read-only by the CPU but is read/write by the HPI port. The contents of this register

have the same effect as the Breakpoint register [0xC014]. This special Breakpoint register is used by software debuggers which

interface through the HPI port instead of the serial port.

When the program counter matches the Breakpoint Address, the INT127 interrupt triggers. To clear this interrupt, a zero value

must be written to this register.

ID to HPI Enable (Bit 14)

The Interrupt Routing register allows the HPI port to take over

some or all of the SIE interrupts that usually go to the on-chip

CPU. This register is read-only by the CPU but is read/write by

the HPI port. By setting the appropriate bit to ‘1’, the SIE

interrupt is routed to the HPI port to become the HPI_INTR

signal and also readable in the HPI Status register. The bits in

this register select where the interrupts are routed. The

individual interrupt enable is handled in the SIE interrupt

enable register.

The ID to HPI Enable bit routes the OTG ID interrupt to the HPI

port instead of the on-chip CPU.

If enabled, the HPI Mailbox TX Empty interrupt triggers when the external host processor reads from this register. The HPI Mailbox

TX Empty interrupt is automatically cleared when the CY7C67200 writes to this register.

In addition, when the CY7C67200 writes to this register, the HPI_INTR signal on the HPI port asserts signaling the external

processor that there is data in the mailbox to read. The HPI_INTR signal deasserts when the external host processor reads from

this register.

CPU write to the

HSS_TxData register

0 min, BT max when starting from IDEL.

For back to back transmit, new START Bit

begins immediately following previous STOP bit.

(BT = bit period)

qt_clk, CPU_A, CPUHSS_cs, CPU_wr are internal signals, included in the diagram to illustrate relationship between CPU opera-

tions and HSS port operations.

Bit 0 is LSB of data byte. Data bits are HIGH true: HSS_TxD HIGH = data bit value ‘1’.

BT = bit time = 1/baud rate.

HSS Block Mode Transmit

HSS_TxD

GAP

BLOCK mode transmit timing is similar to BYTE mode, except the STOP bit time is controlled by the HSS_GAP value.

The BLOCK mode STOP bit time, t_GAP= (HSS_GAP – 9) BT, where BT is the bit time, and HSS_GAP is the content of the HSS

Transmit Gap register 90xC074].

The default t_GAPis 2 BT.

BT = bit time = 1/baud rate.

Receive data arrives asynchronously relative to the internal clock.

Incoming data bit rate may deviate from the programmed baud rate clock by as much as ±5% (with HSS_RATE value of 23 or

higher).

BYTE mode received bytes are buffered in a FIFO. The FIFO not empty condition becomes the RxRdy flag.

BLOCK mode received bytes are written directly to the memory system.

Bit 0 is LSB of data byte. Data bits are HIGH true: HSS_RxD HIGH = data bit value ‘1’.

BT = bit time = 1/baud rate.

HSS_RTS

HSS_CTS

HSS_TxD

Start of transmission not delayed by HSS_CTS

Start of transmission delayed until HSS_CTS goes high

t_CTSset-up: HSS_CTS setup time before HSS_RTS = 1.5T min.

_CTShold: HSS_CTS hold time after START bit = 0 ns min.

T = 1/48 MHz.

When RTS/CTS hardware handshake is enabled, transmission can be held off by deasserting HSS_CTS at least 1.5T before

HSS_RTS. Transmission resumes when HSS_CTS returns HIGH. HSS_CTS must remain HIGH until START bit.

HSS_RTS is deasserted in the third data bit time.

An application may choose to hold HSS_CTS until HSS_RTS is deasserted, which always occurs after the START bit.
