#INT_DEFAULT
Syntax:
#INT_DEFAULT
Elements: None
Purpose:
The following function will be called if the PIC? triggers an interrupt and none of the
interrupt flags are set. If an interrupt is flagged, but is not the one triggered, the
#INT_DEFAULT function will get called.
Examples: #int_default
default_isr() {
printf("Unexplained interrupt\r\n");
}

#INT_GLOBAL
Syntax:
#INT_GLOBAL
Elements: None
Purpose:
This directive causes the following function to replace the compiler interrupt
dispatcher. The function is normally not required and should be used with great
caution. When used, the compiler does not generate start-up code or clean-up
code, and does not save the registers.
Examples: #int_global
isr() {
#asm
// Will be located at location 4 for PIC16 chips.
bsf
isr_flag
retfie
#endasm
}
