When no configuration errors are present, the words will have a value of 0x0000
(hexadecimal). Configuration errors should be corrected to have the module
perform as required by the application.
Additionally, each command in the user command list contains an error status
data area. This data can be viewed through the debug/configuration port. This
data can be configured to be placed in the module's database with each register
containing an error value for each command for each port as shown in the
following diagram:
