#INT_EXT_H2L problem PIC12F1822

[colin382]

Trying to create an external interrupt that will fire on a high-to-low transition
using compiler version 5.105.12.10

#include <12F1822.h>

This compiles:
#INT_EXT
void command_rx(){
output_toggle(PIN_A2);
}

This doesn't, gives "Invalid Pre-Processor directive" error:
#INT_EXT_H2L // copied from 12F1822.h
void command_rx(){
output_toggle(PIN_A2);
}

Do I need to declare the pin for which the interrupt applies? If so, how?

PS

#INT_IOC_A1_H2L doesn't work either!

Understand the difference between the physical interrupt, and the
programming commands.

The interrupt is still INT_EXT.

The H2L instruction, is for use when enabling the interrupt and disabling
it, and what it does is program INT_EXT, to trigger on the specified
condition.

So your do not use INT_EXT_H2L as the interrupt. It isn't. You only use
this in the command to enable/disable the interrupt.

Thanks Ttelmah, helpful as always. All working now.
