4.29 vector Pragma

The IAR vector pragma sets the interrupt number associated with the following interrupt handler function.

Suggested Replacement

Remove the pragma and ensure that the vector number has been specified as the argument to the __interrupt qualifier used with the interrupt function.

Caveats

None

Examples

Consider migrating IAR code such as:

volatile int x;
#pragma vector=2
void __interrupt incIsr(void) {
    x++;
}

to MPLAB XC8 code similar to:

#include <xc.h>
 
volatile int x;
void __interrupt(2) incIsr(void) {
    x++;
}

Further Information

See the Interrupts section in the MPLAB XC8 C Compiler User's Guide for AVR MCUs for more information on writing interrupt functions.
