SSP2INT

SSP2_INT -- (M)SSP module 2

Uses PIR4,SSP2IF, PIE4,SSP2IE 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.
Example:
@ INT_DISABLE SSP2_INT

ASM

 INT_LIST     macro     ;IntSource      Label,    Type,    ResetFlag?
            INT_Handler  SSP2_INT     _GetData   PBP       Yes
            endm
            INT_CREAT               ;Creates the interrupt processor
            INT_ENABLE    SSP2_INT  ;enables SSP2 interrupts

ENDASM

Command functions:
INT_CREATE ;Creates the interrupt processor
INT_ENABLE SSP2_INT enable SSP2 interrupt.
INT_DISABLE SSP2_INT disable SSP2 interrupt.
INT_CLEAR SSP2_INT clear flags
INT_RETURN ---------- To restore and return to the program where interrupt was made.
