Data Polling Flash
1042H–AVR–04/03
When a byte is being programmed into the Flash, reading the address location being
programmed will give the value $FF. At the time the device is ready for a new byte, the
programmed value will read correctly. This is used to determine when the next byte can
be written. This will not work for the value $FF, so when programming this value, the
user will have to wait for at least t
erased device contains $FF in all locations, programming of addresses that are meant
to contain $FF can be skipped.
