R_SCI_Receive

Remarks (2/2) • If callback function func1 is specified, callback functions are executed by the interrupt processing

function. This means that no other interrupt can be processed until a callback function has completed.

Program example

/* PDL functions */

#include “r_pdl_sci.h”

/* PDL device-specific definitions */

#include “r_pdl_definitions.h”

volatile uint8_t gSCI1ReceiveBuffer[10];

/* SCI channel 1 receive data handler */

void SCI1RxFunc(void){}

/* SCI channel 1 error handler */

void SCI1ErrFunc(uint8_t error_flags){}

/* SCI channel 1 break signal handler */

void SCI1BreakFunc(void){}

void func( void )

{

uint8_t temp;

/* Put a Null character at the end of the string */

gSCI1ReceiveBuffer[10] = NULL;

R_SCI_Receive(

&c_ gSCI1ReceiveBuffer,

SCI1RxFunc,

SCI1ErrFunc,

SCI1BreakFunc

);
