;R12 contains the segment offset address to be
;programmed
;R13 contains the data to be programmed
;use EXTended addressing for next MOV instruction
;command cycle 4: the EPC starts execution of
;Programming Command
;use EXTended addressing for next MOV instruction
;read Flash Status register (FSB) in R7
;save it in R6 register
;Check if FSB.7 = Data.7 (i.e. R7.7 = R13.7)
;Check if FSB.5 = 1 (Programming Error)
;Programming Error: verify is Flash programmed
;data is OK
;use EXTended addressing for next MOV instruction
;read Flash Status register (FSB) in R7
;Check if FSB.7 = Data.7
;Programming failed: Flash remains in Write
;Operation.
;To go back to normal Read operations, a Read/Reset
;command
;must be performed
;load register R7 with Read/Reset command
;use EXTended addressing for next MOV instruction
;address is don’t care for Read/Reset command
;here place specific Error handling code
;When programming operation finished succesfully,
;Flash is set back automatically to normal Read Mode
