Do 1 byte address checks first prior to doing 2 byte address checks. When performing 2 byte addressing on 1 byte addressing eeprom, the second byte is taken in as a write operation and ends up erasing the eeprom region we want to preserve. While we could have theoretically handled this by ensuring the write protect of the eeproms are properly managed, this is not true in case where board are updated with 1 byte eeproms to handle supply status. Flipping the checks by checking for 1 byte addressing prior to 2 byte addressing check prevents this problem at the minor cost of additional overhead for boards with 2 byte addressing eeproms.
