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 );
}
