5.3.2 EIP Status Data in Upper Memory
The EIP driver has an associated status data area located in the upper memory
of the PLX32-EIP-MBTCP-UA. The Data Map functionality of the PLX32-EIP-
MBTCP-UA can be used to map this data into the normal user data range of the
PLX32-EIP-MBTCP-UA database.
Note that all the status values are initialized to zero (0) at power-up, cold boot
and during warm boot.

UA stores general error and status data for each EIP connected and
