When using the MR30 OS-independent interrupt and enabling the multiple interrupts option, I enable it with "#pragma

INTERRUPT /E".

Is there a similar option for enabling multiple interrupts when using in the OS-dependent interrupt? I want to use the C language to

write the source file.

MR30 is not equipped with a function such as "#pragma", which enables multiple interrupts for the OS-dependent interrupt. Use the

following to describe the area in which you want to enable multiple interrupts.

#include <mr30.h>

#include "id.h"

void inthand (void) /* OS-dependent interrupt handler */

{

/* multiple-interrupt inhibited area */

asm(" FSET I");

/* multiple-interrupt enabled area */

asm(" FCLR I"); <--- delete if there are no interrupt-inhibit

areas after this point.

/* multiple-interrupt inhibited area */

}

Cyclic handlers and alarm handlers are in the multiple-interrupt enabled state.
