5.1.7

5.1.7 Update EEPROM Checksum

Update EEPROM Checksum

The Host issues this command to a transceiver to recalculate the checksum. The Host typically issues
this command after it has completed writing data to the EEPROM. The Host must wait for the

Acknowledge

Acknowledge command before issuing any additional commands.

Example: 8C|00|00|8C (There are no Data bytes for this command)

Acknowledge: 8C|00|00|8C

5.1.8

5.1.8 Check EEPROM Checksum

Check EEPROM Checksum

The Host issues this command to a transceiver to validate the EEPROM checksum. The Host typically
issues this command after resetting a transceiver. A transceiver replies with a valid or invalid
checksum by sending back the

EEPROM Checksum Status

EEPROM Checksum Status command.

Example: 8D|00|00|8D (There are no Data bytes for this command)

EEPROM Checksum Status: 8E|01|00|01|8E

5.1.9

5.1.9 EEPROM Checksum Status

EEPROM Checksum Status

A transceiver issues this command to the Host in response to a

Check EEPROM Checksum

command. A Data value of 00h indicates an invalid Checksum while a value of 01h indicates a valid
Checksum.
