6.1.8

 

Update EEPROM Checksum*

This command is sent by the Host to the AeroComm module to tell it to recalculate the checksum.

This is typically done by the Host CPU after it has completed writing data to the EEPROM on the
AeroComm module. The response to this command is an acknowledge.

6.1.9

 

Check EEPROM Checksum*

This command is sent by the Host CPU to the AeroComm module to validate the EEPROM

checksum. This is typically done after bringing up the AeroComm module out of reset. The AeroComm
module reports either a good or a bad checksum, by sending back a response called 

EEPROM Checksum

Status

6.1.10

 

EEPROM Checksum Status*

This command is sent by the AeroComm module in response to a 

Check EEPROM Checksum

command from the Host CPU. The data portion of the command indicates whether the checksum is good or
bad, based on which the Host CPU takes the appropriate action.

6.1.11

 

Acknowledge*

Some commands in the above set have an implied positive response.  The generic positive

response is defined as the command sequence just received retransmitted back with a zero length.
