The Host issues this command to a ConnexLink 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 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

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

A ConnexLink issues this command to the Host in response to a Check EEPROM Checksum Check EEPROM Checksum Check EEPROM Checksum Check EEPROM Checksum
command. A Data value of 00h indicates an invalid Checksum while a value of 01h indicates a
valid Checksum.
