; Disable ints so required sequences will execute properly
; Load lower 8 bits of erase address boundary
; Load upper 6 bits of erase address boundary
; Point to program memory
; Not configuration space
; Specify an erase operation
; Enable writes
; Start of required sequence to initiate erase
; Write 55h
;
; Write AAh
; Set WR bit to begin erase
; Any instructions here are ignored as processor
; halts to begin erase sequence
; Processor will stop here and wait for erase complete.
; after erase processor continues with 3rd instruction
; Disable writes
; Enable interrupts
