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

Summarises processing by the API

function.

Prototype

The function format and a brief explanation of the arguments.

Description Explains how to use the API function and shows assignable parameters separating each

argument with [argument].

Return value

Describes the returned value of the API function.

Category

Indicates the category of the API function.

Reference

Indicates the API functions to be referred.

Remark

Describes notes to use the API function.

Program example Represents how to use the API function by a program example.

Two examples of return value checking are shown below.

/* PDL definitions */

#include “r_pdl_pfc.h”

#include “r_pdl_sci.h”

/* PDL device-specific definitions */

#include “r_pdl_definitions.h”

/* Application-specific definitions */

#include <stddef.h>

void func( void )

{

bool result;

/* Write 0xFF to register PFC1 */

result = (R_PFC_Write(

0xFF

);

if (result == false)

{

/* Handle the error here */

}

/* Keep trying to send a string (if the channel is busy) */

{

result = R_SCISendString(

“Renesas RX”,

NULL,

PDL_NO_FUNC

);

} while (result == false);

)

For clarity, the return value is not checked in the examples used in this manual.
