Interrupt control
Reference
None.
Remarks
•
The selected interrupt pin is enabled automatically.
•
Port Function Control registers PF8IRQ or PF9IRQ are modified to select the A or B IRQn pin.
For smaller device packages, some A or B options are removed.
For the 85-pin package, IRQ5, IRQ6 and IRQ7 are not available.
•
The appropriate I/O port ICR and DDR registers are modified.
•
Please see the notes on callback function use in §6.
•
The NMI callback function should not return. It should stop operation or reset the system.
•
If the NMI interrupt fails to initialise, this function will return false.
Program example
/* RPDL definitions */
#include "r_pdl_intc.h"

#include "r_pdl_definitions.h"
/* Declaration of callback function */
void CallBackFunc( void );
void func( void )
{
/* Configure the IRQ13 interrupt on pin IRQ13-A */
R_INTC_CreateExtInterrupt(
PDL_INTC_IRQ13,
PDL_INTC_FALLING | PDL_INTC_A,
