CCP1_INT -- Comparator 1

Uses PIR2,C1IF, PIE2,C1IE 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  CCP1_INT     _GetData   PBP       Yes
            INT_CREAT           ;Creates the interrupt processor
            INT_ENABLE    CCP1  ;enables CCP1 interrupts


INT_ENABLE CCP1_INT – enable CCP1 interrupt.
INT_DISABLE CCP1_INT– disable CCP1 interrupt.
INT_CLEAR CCP1_INT – clear flags
INT_RETURN ---------- To restore and return to the program where interrupt was made.
