BUS2_INT -- Bus Collision 2
Uses PIR4,BCL2IF, PIE4,BCL2IE 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 BUS2_INT
ASM
INT_LIST macro ;IntSource Label, Type, ResetFlag? INT_Handler BUS2_INT _GetData PBP Yes endm INT_CREAT ;Creates the interrupt processor INT_ENABLE BUS2_INT ;enables BUS2 interrupts
ENDASM
INT_ENABLE BUS2_INT – enable BUS2 interrupt.
INT_DISABLE BUS2_INT – disable BUS2 interrupt.
INT_CLEAR BUS2_INT – clear flags
INT_RETURN ---------- To restore and return to the program where interrupt was made.
