5.6.4 MNET Client Command List Error Data
Each command in the command list for the MNET client has a reserved word
value for a status/error code. This error data list can be read using the
Debug/Config Port and can be placed in the module’s internal database. Each
network client has its own register location parameter.
The first word in the register location defined contains the status/error code for
the first command in the client’s command list. Each successive word in the
command error list is associated with the next command in the list. Therefore, the
size of the data area is dependent upon the number of commands defined. The
structure of the data area is displayed below:
Internal Database Address (Example) Offset Description
6010 0 Command #0 Error Status
6011 1 Command #1 Error Status
6012 2 Command #2 Error Status
6013 3 Command #3 Error Status
6014 4 Command #4 Error Status
. .

6107 97 Command #97 Error Status
6108 98 Command #98 Error Status
6109 99 Command #99 Error Status
Note that the values in the Command List Error Status tables are initialized to
zero (0) at power-up, cold boot and during warm boot. Refer to the next section
containing Error Codes to interpret the status/error codes present in the data
area.
