FIQ handler in C

Michael Sch,
Intellectual 800 points

Hi,

what do I need to take care about when implementing FIQ handers written in C?

Can I mark the functions with the following pragma to get advantage of the banked FIQ registers R8 to R12?

#pragma INTERRUPT ( my_isr, FIQ );

Is there anything else to be considered?

Kind regards,
Michael
