SSP1_INT -- (M)SSP module 1

Uses PIR1,SSP1IF, PIE1,SSP1IE 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  SSP1_INT     _GetData   PBP       Yes
            INT_CREAT               ;Creates the interrupt processor
            INT_ENABLE    SSP1_INT  ;enables SSP1 interrupts


Command functions:
INT_CREATE ;Creates the interrupt processor
INT_ENABLE SSP1_INT enable SSP1 interrupt.
INT_DISABLE SSP1_INT disable SSP1 interrupt.
INT_CLEAR SSP1_INT clear flags
INT_RETURN ---------- To restore and return to the program where interrupt was made.
