Format:
PRAGMA INTERRUPT { FAST | RAW | NORMAL | }
This must be used within a procedure that takes no parameters. It
defines the procedure as an interrupt entry point. Such a procedure
is added to a chain of procedures executed whenever an interrupt
hits. Once a procedure has been marked interrupt, it cannot be
called directly by the program.
W, STATUS, PCLATH, FSR, TBLPTR and _picstate are saved on ISR entry and restored on exit
_pic_state is *not* saved or restored. In this case, the interrupt procedure should be written entirely in assembly to avoid corrupting the pic_state area.
*None* of the normal pre-amble or cleanup code is generated. The user is entirely responsible for the interrupt. The code is guarenteed to placed at the interrupt vector.
