; 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 (common RAM)
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
