EXAMPLE 18-2:
WRITING TO FLASH PROGRAM MEMORY
; This write routine assumes the following:
; 1. A valid starting address (the least significant bits = ‘00000’)is loaded in ADDRH:ADDRL
; 2. The 64 bytes of data are loaded, starting at the address in DATADDR
; 3. ADDRH, ADDRL and DATADDR are all located in shared data memory 0x70 - 0x7f
