Built-in Functions
should have been defined for the indicated interrupt.
The GLOBAL level will not enable any of the specific interrupts, but will allow
any of the specified interrupts previously enabled to become active. Some
chips that have an interrupt on change for individual pins all the pin to be
specified, such as INT_RA1. For interrupts that use edge detection to
trigger, it can be setup in the enable_interrupts( ) function without making a
separate call to the set_int_edge( ) function.
Enabling interrupts does not clear the interrupt flag if there was a pending
interrupt prior to the call. Use the clear_interrupt( ) function to clear pending
interrupts before the call to enable_interrupts( ) to discard the prior interrupts.
