2. Driver
2.1 Overview
The library described herein provides a peripheral facility control program (peripheral
driver) for microcomputers. Use of the Renesas API permits the peripheral driver to be
built into a user program.
2.2 Driver Features
The library described herein has the following features available as a peripheral driver.
(1) Serial I/O control feature
It comprises a serial interface driver, which sets or clears the conditions of serial
communication, as well as controls and manages the transmission/reception of
communication data.
(2) Timer control feature
It comprises a timer driver, which sets or clears the operating conditions of timers,
as well as controls the timer operation.
(3) I/O port control feature
It comprises an I/O port driver, which sets or clears the usage conditions of I/O ports, as
well as control data read/write operation.
(4) External interrupt control feature
It comprises an external interrupt driver, which sets or clears the usage conditions of
external interrupts, as well as controls interrupt operation.
(5) A/D converter control feature
It comprises an A/D converter driver, which sets or clears the usage conditions of A/D
converters, as well as controls A/D converter operation.

2.3 Serial Interface Driver
The serial interface driver sets serial communication, clears settings, transmit/receives
data, and controls the status of serial communication.
There are two kinds of serial interface driver: a single-data transmission/reception API
and a multi-data transmission/reception API.

2.4 Timer Driver
The timer driver sets the timer, clears timer settings, controls timer operation, and
acquires a counter value with respect to the following modes:
• Timer mode
• Event counter mode
• Pulse width modulation mode (PWM mode)
• Pulse period measurement mode
• Pulse width measurement mode
2.4.1 Timer Mode
In this mode, the timer counts the internally generated count source. When an
underflow or an overflow interrupt occurs, it calls a preset callback function.
2.4.2 Event Counter Mode
In this mode, the timer counts the external signal fed in from an input pin or an
overflow or underflow from other timer. When an underflow or an overflow interrupt
occurs, it calls a preset callback function.
2.4.3 Pulse Width Modulation Mode (PWM Mode)
In this mode, the timer outputs pulses in a given width successively. When an
underflow or an overflow interrupt occurs, it calls a preset callback function.
2.4.4 Pulse Period Measurement Mode
In this mode, the timer measures the pulse period of an external signal fed in from an
input pin. When an underflow or an overflow interrupt occurs, it calls a preset callback
function.
2.4.5 Pulse Width Measurement Mode
In this mode, the timer measures the pulse width of an external signal fed in from an
input pin. When an underflow or an overflow interrupt occurs, it calls a preset callback
function.

2.5 I/O Port Driver
The I/O port driver sets the I/O port for input or output, writes data to the I/O port, and
reads data from the I/O port.

settings of the A/D converter, acquires the A/D converter value, acquires the status of the
A/D converter, and clears the status of the A/D converter.

3. Standard Types
This section describes the standard types defined in the library. For details about the
set values, refer to the description of each API.
Standard type
Description
Boolean
The Boolean type represents the enum-type data that indicates
whether successful (RAPI_TRUE (= 1)) or failed (RAPI_FALSE (=
0)).
VoidFuncNotify
The VoidFuncNotify type represents the type of the notification
function to be registered.
