GPC_INT -- GPIO Int On Change

Uses INTCON,GPIF, GPIE Registers and Control Bits.
DT's Interrupts MUST be used with PicBasic Pro and MPASM.

The following block of instructions will establish the interrupt used and the PBP label (your ISR) to jump to once interrupt occurs. Remember; all PBP labels or variables used inside ASM code blocks must be preceded by the underscore,( _GetData). All instruction to the interrupt processor should be in ASM and preceded by the @ symbol and to the far left column of the editor if not included in other ASM code blocks.


 INT_LIST     macro     ;IntSource      Label,    Type,    ResetFlag?
            INT_Handler  GPC_INT     _GetData   PBP       Yes
            INT_CREAT             ;Creates the interrupt processor
            INT_ENABLE   GPC_INT  ;enables GPC interrupts


Command functions:
INT_CREATE ;Creates the interrupt processor
INT_ENABLE GPC_INT – enable GPC interrupt.
INT_DISABLE GPC_INT– disable GPC interrupt.
INT_CLEAR GPC_INT – clear flags
INT_RETURN ---------- To restore and return to the program where interrupt was made.
