PRODUCT OVERVIEW  
2.1.  
INTRODUCTION  
The i4000 provides a compact high-performance VMEbus gateway to the M-module interface. The i4000 has  
a 6U form factor. Four M-modules can be mounted on the i4000.  
The M-module interface of the i4000 complies with the M-module Specification. The M-module specification is  
ANSI approved. The M-module interface features A8, A24, D16 and D32 access types.  
2.2.  
TECHNICAL OVERVIEW  
Below an overview of the i4000 is listed.  
VME interface  
A24/A16, D16/D08(EO)  
D08(O) (DYN) interrupt vector (vector unique per module)  
I(x) interrupt level (on the i4000/NP2 this is programmable per module)  
M-module interface  
4 M-module Interfaces (A08/A24, D16/D32)  
INTA software-end-of interrupt  
INTB hardware-end-of-interrupt  
INTC interrupt-vector-transfer  
Connections  
Via 25 pole sub-D connector on the front of the M-module  
Via 24 pole I/O connector on the i4000 for rear I/O (only on the i4000/P2 version)  
Via P1 to VMEbus  
Via VME-P2 connector (only on the i4000/P2 version)  
Note: The P2 on an i4000/P2 can be used to create an alternative I/O-path for M-modules placed on the  
carrier board. The M-modules must support an alternative I/O-path (usually recognizable by a 24-pole  
female header near the DSUB-25).  
IMPORTANT: The i4000/P2 cannot be used in a VMEbus rack with monolithic backplane or a P2/J2  
backplane. For these cases use an i4000/NP2 instead.

INSTALLATION AND SETUP  
3.1.  
UNPACKING THE HARDWARE  
The hardware is shipped in an ESD protective container. Before unpacking the hardware, make sure that this  
takes place in an environment with controlled static electricity. The following recommendations should be  
followed:  
Make sure your body is discharged to the static voltage level on the floor, table and system chassis by  
wearing a conductive wrist-chain connected to a common reference point.  
If a conductive wrist-chain is not available, touch the surface where the board is to be put (like table,  
chassis etc.) before unpacking the board.  
Leave the board only on surfaces with controlled static characteristics, i.e. specially designed anti  
static table covers.  
If handling the board over to another person, touch this persons hand, wrist etc. to discharge any  
static potential.  
IMPORTANT: Never put the hardware on top of the conductive plastic bag in which the hardware is  
shipped. The external surface of this bag is highly conductive and may cause rapid static  
discharge causing damage. (The internal surface of the bag is static dissipative.)  
Inspect the hardware to verify that no mechanical damage appears to have occurred. Please  
report any discrepancies or damage to your distributor or to AcQuisition Technology  
immediately and do not install the hardware.

CONNECTORS  
3.2.1. MOUNTING AN M-MODULE  
Four M-modules can be fitted on the i4000 carrier board. To plug in a module, position the 2-row 40 pole or  
3-row 60-pole M-module interface connector of the module above the 2-row header P1 of the i4000. Then  
push the module until the header connector is positioned and press the module with care in its place.  
Note: With 3-row M-modules row C of the M-module interface connector is left unoccupied.  
The module should be secured in its position using four screws (M3 * 5mm), refer to figure 1 for the positions  
of the mounting screws.

3.2.2. P2 CONNECTOR ASSIGNMENTS (I4000/P2 ONLY)  
Peripherals can be connected to M-modules in two ways. On the front of the M-module a 25-pole sub-D  
connector (or mechanically equivalent) can be used to connect cables on the front panel of the VMEbus base  
board. Alternatively a 24-pole header connector interfaces the I/O signals to the base board where they are  
connected to the VMEbus P2 connector.  
In 32-bit VMEbus systems the backplane for the P2 connector must either be removed for the i4000 slot or an  
i4000 without the P2 connector must be ordered. In that case the peripherals only can be connected to the  
M-module up front.

Figure 2  
Every M-module has 24 pins of the P2 connector assigned. This way four modules on a base board can use  
this I/O path.  
This division into four pads of the P2 connector enables the so called “module connector” to be plugged into  
the back of a 96-way shroud, mounted on the “P2-backplane”. On the 96-way connector 3 pins are not used  
for every module. Several manufacturers produce these “module connectors”, which can be coded and  
sometimes have latches.

VMEBUS INTERFACE  
4.1.  
ADDRESS INTERFACE  
The i4000 can be selected to accept either short addressing, using 16-bit addresses (A16) or standard  
addressing, using 24-bit addresses (A24).  
When using short addressing up to 32 i4000 boards can be put in a single VMEbus system since the lower 11  
address lines (A0-A10) are used internally on the i4000. If standard addressing is used, a larger address  
space is available to select the board.  
The memory space occupied by the i4000 is 0x800 bytes long. This memory space is equally spread across  
the four modules. So each module occupies 0x200 bytes. From these 0x200 bytes address space half is used  
by the interrupt controller. The address space for each module is therefore 0x100 bytes long (8 bit  
addressing).  
The address space of the i4000 is selectable using dip switches (SW1 and SW2) which are accessible even  
when the four module slots are occupied. When a switch is “on” the corresponding address line is a logical  
“zero” and when a switch is “off” the corresponding address line is “one”.  
Address modifier AM4 can be used to select either standard or short memory addressing. If AM4 is “one” (the  
switch is in the off position) standard addressing is selected. If AM4 is “zero” (switch on) short addressing is  
selected. When using short addressing the address lines A16-A23 are don’t cares.

4.2.  
THE INTERRUPTER  
The i4000 has a interrupter which is largely compatible with the MC68C153. The interrupter is a so called  
D08(O) type interrupter which means that the interrupter during an interrupt acknowledge cycle will put a  
status byte on the data lines D0-D7.  
The interrupter uses a fixed interrupt level (IRQ1-IRQ7 set by SW1) for all M-modules. The i4000/NP2 also  
can be set to “software programmable level”, the interrupt level for an M-module has to be programmed using  
the control registers. Each M-module can generate its own vector.

There are two classes of interrupters which are both supported by the i4000: release on acknowledge (ROAK)  
or release on register access (RORA). The ROAK interrupter negates its interrupt request line in response to  
an interrupt acknowledge cycle. This mechanism will work with all handlers. The RORA interrupter releases  
its request when the handler accesses an on-board register during the interrupt service routine. The handler  
performs the acknowledge cycle but the interrupter does not immediately negate its request. Sometime during  
the service routine the handler will have to write to a register on the interrupter which causes it to negate the  
request.

FUNCTIONAL DESCRIPTION  
5.1.  
BLOCK DIAGRAM  
Figure 7 i4000 block diagram  
The interrupt controller used on the i4000 is largely compatible with the MC68153 interrupt controller from  
Motorola.  
The interrupt controller provides means for the modules to ask for an interrupt of the processor activity and  
receive service from the processor. The interrupt controller on the i4000 acts as an interface device  
requesting and responding to interrupt acknowledge cycles for up to 4 independent modules.  
5.1.1. REGISTER DESCRIPTION  
The interrupt controller of the i4000 contains 8 programmable registers. There are four control registers (CR0-  
CR3) that control the operation of the interrupt controller and four vector registers (VR0-VR3) that contain the  
vector data used during an interrupt acknowledge cycle. Every module is assigned one register pair.

5.1.2. ADDRESS MAPPING  
As mentioned before the address space occupied by the i4000 board is 0x800 bytes (A0-A10). These 0x800  
bytes are divided into 4 identical spaces. Every 0x200 bytes block is assigned to a module slot. The first  
0x100 bytes address space are assigned to the module itself and the second 0x100 bytes are used for the  
access part of the interrupt controller.  
Using this method of address decoding provides an identical address map of each module on the i4000  
board. This makes writing the software easier since just the base address of the module, not the base  
address of the i4000 has to be known. Every module has its own Interrupt-Vector and Interrupt-Control  
register. The 0x100 bytes from each module used to access the interrupt controller are not completely  
decoded. Both registers of the interrupt controller are mirrored several times within the 0x100 bytes address  
space. Decoding of the M-module’s 0x100 bytes of address space is done on the used M-module.

The base address of a module can be calculated using the following formula:  
ModuleBaseAddress = i4000BaseAddress + ModuleNumber * 0x200  
EXAMPLE:  
The installed base address of the i4000 is 0x800000. A module is fitted into slot 2. The module base address  
is then 0x800000 + 2 * 0x200 = 0x800400. When using a 32 bit master, which accesses the standard address  
space at address 0xff??????, the module will be accessed at address 0xff800400. The corresponding  
interrupt control register address is then 0xff800501.

L2-L0 (Interrupt level)  
The least significant 3-bit field of the register determines the level at which an interrupt will be  
generated. These three bits are only used in the i4000/NP2 interrupt controller, if the interrupt level  
dipswitches are set to software irq level (all “on”). The level can be programmed from “1 to 7”.  
Note: The i4000/P2 only supports interrupt levels set by dipswitches, it is advisable to program the level, set  
by dipswitches, also in the register. This to maintain software compatibility with other similar boards.  
IRAC (Interrupt Auto-Clear)  
If the IRAC is set (bit 3), IRE (bit 4) is cleared during an interrupt acknowledge cycle responding to  
this request. This action of clearing IRE disables the module interrupt request. To re-enable the  
module interrupt request associated with this register, IRE must be set again by writing to the control  
register.  
IRE (Interrupt enable)  
This field (bit 4) must be set (high level) to enable the module interrupt request associated with the  
control register. If the module asserts IRQ, but IRE is cleared, no interrupt request to the VMEbus will  
be generated.  
X/IN* (External/Internal)  
Bit 5 of the control register determines the response of the i4000 interrupt controller during an  
interrupt acknowledge cycle. If the X/IN* bit is cleared (low level) the interrupt controller will respond  
with vector data and a DTACK* signal, i.e., an internal response. If X/IN* is set, the vector is not  
supplied and no DTACK* is given by the interrupt controller, i.e., an external module should respond.  
RESERVED  
These two bits are not used in the current implementation of the interrupt controller and are reserved  
for future use.  
5.1.4. VECTOR REGISTERS  
Each module interrupt has its own associated vector register. Each register is 8 bits wide and supplies a data  
byte during its interrupt acknowledge cycle, if the associated External/Internal (X/IN*) control register bit is  
clear (zero). This data can be status, identification, or address information depending on system usage. The  
information is programmed by the system user.  
5.1.5. INTERRUPT CONTROLLER RESET  
When a VMEbus reset is applied, the control registers of the i4000 interrupt controller are set to all zeros  
(low). The vector registers however are uninitialized and should be programmed before use.
