Port 1 Command Error List Layout
The first word in the specified register location contains the status/error code for
the first command in the port's
Command List
. Successive words in the
Command Error List
are associated with corresponding commands in the list.
The addresses listed are for Port 1 only; but the format is the same for each port.
See Master Port: Command List Errors (page 130) for the start address for each
port.

Note that the gateway initializes the Command Error List tables to zero (0) at
power-up, cold boot, and warm boot. If a command executes successfully, the
value in the associated register remains at zero (0), indicating no command error
was detected. Any non-zero value in this table indicates the corresponding
command experienced an error.
The data in this table is dynamic and is updated each time a command is
executed. Therefore, if the command fails once and succeeds on the next
attempt, the error code from the previously failed attempt is overwritten with zero
and be lost. Error codes are not archived in the gateway's database. To see if the
port has experienced an error since the most recent restart and what the most
recently occurring error was, if any, you can check the
Last Error/Index
.
