how to allow the global interrupts in the 24FJ family pics?

Hi guys,

Would anybody tell me how to enable the global interrupts in the pic24fj256GB106?

The compiler doesn't like:
Code:

enable_interrupts(GLOBAL);

Undefined Identifier GLOBAL he says.

Any idea?

Much 10x in advance...

The 'reason', is that the PIC24, has interrupt levels.
You can enable/disable the individual 'levels', with (for example)
disable_interrupts(INTR_LEVEL4);

The equivalent to the old 'global', is:

enable_interrupts(INTR_GLOBAL), which turns on all the levels.

Best Wishes
