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

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. 7 Rev.1.00 2007.11.1 REC10B0002-0100

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

2.7 A/D Converter Driver The A/D converter driver sets the A/D converter, controls the A/D converter, clears 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. 11 Rev.1.00 2007.11.1 REC10B0002-0100

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. 12 Rev.1.00 2007.11.1 REC10B0002-0100

4.2 Description of Each API This section describes each API and explains how to use them, showing a program example for each. The description of each API is divided into the following items. • Synopsis : Outlines the content of processing performed by the function. It also shows the syntax of the function, followed by a brief explanation of arguments. • Description : Describes the function and how to use it in detail. • Return value : Explains the returned value of the function.

If the API is used in clock synchronous serial communication mode, do not set these values. (UART0, UART1, UART2) RAPI_PARITY_NON No parity bit RAPI_PARITY_EVEN Even parity bit RAPI_PARITY_ODD Odd parity bit For the clock polarity of serial communication, the following values can be set. If the API is used in clock asynchronous serial communication mode, do not set these values. (UART0, UART1, UART2) RAPI_DPOL_NON Polarity not invertedRAPI_DPOL_INV Polarity inverted

If serial communication was successfully set, RAPI_TRUE is returned; if settings failed, RAPI_FALSE is returned. Functionality Serial I/O Reference Remark If an undefined value is specified in the first argument, operation of the API cannot • be guaranteed. Program example #include ”rapi_sif_m16c_62p” Boolean func( void ) { /* Set the data of RAPI_COM1 to serial driver */ Return _BasicSetSerialFormat(RAPI_COM1 | RAPI_SM_SYNC | RAPI_CKDIR_INT | RAPI
