7. At the end of the programming session, RESET can be set high to commence
8. Power-off sequence (if needed):
When a byte is being programmed into the Flash or EEPROM, 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
the next byte. As a chip-erased device contains $FF in all locations, programming of
addresses that are meant to contain $FF can be skipped. This does not apply if the
EEPROM is reprogrammed without chip-erasing the device. In that case, data polling
cannot be used for the value $FF, and the user will have to wait at least t
before programming the next byte. See Table 28 for t
