EEINT

EE_INT -- EEPROM/FLASH Write Complete Function

Uses PIR2,EEIF, PIE2,EEIE 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 EE_INT

ASM

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

ENDASM

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

NOTE: Interrupt flag bit EEIF of the PIR2 register is set when write is complete. It must be cleared in the software.
