Reference

__BasicOpenSerialDriver

Remark

The specifiable serial ports differ with each CPU used.

If an undefined value is specified in the argument, operation of the API cannot be

guaranteed.

When used for the H8/300H, this API places a specified serial port into module
standby state after closing it.

Program example

#include ”rapi_sif_r8c_13.h”

void func( void )
{
/* Close serial driver */
return Rapi_BasicCloseSerialDriver( RAPI_COM1 );
}
