These bits are reserved bits in the Atmel
zero.
The EEPROM Address Registers – EEARH and EEARL specify the EEPROM address in
the 512 bytes EEPROM space. The EEPROM data bytes are addressed linearly between
0 and 255/511/511. The initial value of EEAR is undefined. A proper value must be written
before the EEPROM may be accessed.
For the EEPROM write operation, the EEDR Register contains the data to be written to the
EEPROM in the address given by the EEAR Register. For the EEPROM read operation,
the EEDR contains the data read out from the EEPROM at the address given by EEAR.
These bits are reserved bits in the Atmel ATA6612/ATA6613 and will always read as zero
The EEPROM Programming mode bit setting defines which programming action that will
be triggered when writing EEPE. It is possible to program data in one atomic operation
(erase the old value and program the new value) or to split the Erase and Write operations
in two different operations.
