Reading the EEPROM

The algorithm for reading the EEPROM memory is as follows (refer to Programming the Flash for details on Command and Address loading):

  1. 1.Step A: Load Command “0000 0011”.
  2. 2.Step G: Load Address High Byte (0x00 - 0xFF).
  3. 3.Step B: Load Address Low Byte (0x00 - 0xFF).
  4. 4.Set OE to “0”, and BS1 to “0”. The EEPROM Data byte can now be read at DATA.
  5. 5.Set OE to “1”.
