EXAMPLE 11-4:

ERASING ONE ROW OF PROGRAM MEMORY

; This row erase routine assumes the following:

; 1. A valid address within the erase block is loaded in ADDRH:ADDRL

; 2. ADDRH and ADDRL are located in shared data memory 0x70 - 0x7F

BCF

INTCON,GIE

; Disable ints so required sequences will execute properly

BANKSEL

EEADRL

MOVF

ADDRL,W

; Load lower 8 bits of erase address boundary

MOVWF

EEADRL

MOVF

ADDRH,W

; Load upper 6 bits of erase address boundary

MOVWF

EEADRH

BSF

EECON1,EEPGD

; Point to program memory

BCF

EECON1,CFGS

; Not configuration space

BSF

EECON1,FREE

; Specify an erase operation

BSF

EECON1,WREN

; Enable writes

MOVLW

55h

; Start of required sequence to initiate erase

MOVWF

EECON2

; Write 55h

MOVLW

0AAh

;

MOVWF

EECON2

; Write AAh

BSF

EECON1,WR

; Set WR bit to begin erase

NOP

; Any instructions here are ignored as processor

; halts to begin erase sequence

NOP

; Processor will stop here and wait for erase complete.

; after erase processor continues with 3rd instruction

BCF

EECON1,WREN

; Disable writes

BSF

INTCON,GIE

; Enable interrupts
