The Host issues this command to a ConnexLink to write and read EEPROM addresses as well as
for NOP. The Host must wait for the
Diagnostic Result Diagnostic Result Diagnostic Result Diagnostic Result command before issuing any additional
commands. Refer to Section 6, Configuring the AC5124C Section 6, Configuring the AC5124C Section 6, Configuring the AC5124C Section 6, Configuring the AC5124C for the list of configurable EEPROM
parameters.

02h Read EEPROM. Additional data: first 2 bytes
specify starting address. Second 2 bytes specify
ending address.
08h NOP.
09h Write EEPROM. Additional data: first 2 Bytes
specify starting address. Second 2 Bytes specify
ending address. Remaining bytes specify data to
be written. (Range 00h to 7Fh)

Diagnostic Result: 87|02|00|09|00|8C
Any additional sub-commands are reserved by the system and if used may cause system
