Data Polling
1187H–AVR–09/07
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
Flash byte, or t
tains $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
