Data Polling EEPROM
2502K–AVR–10/06
When a new byte has been written and is being programmed into EEPROM, reading the
address location being programmed will give the value 0xFF. At the time the device is
ready for a new byte, the programmed value will read correctly. This is used to deter-
mine when the next byte can be written. This will not work for the value 0xFF, but the
user should have the following in mind: As a chip erased device contains 0xFF in all
locations, programming of addresses that are meant to contain 0xFF, can be skipped.
This does not apply if the EEPROM is reprogrammed without chip erasing the device. In
this case, data polling cannot be used for the value 0xFF, and the user will have to wait
at least t
value.
