Table 46: Narrowband Chipset RAM Test Structure: sNBCS_DIAG_TEST_RAM
Structures in the Driver’s Allocated Memory
These structures are defined and used by the driver and are part of the context memory allocated
when the driver is opened. These structures are the Chipset Module Data Block (CSMDB) and
the Chipset Device Data Block (CSDDB).
Chipset Module Data Block: CSMDB
The CSMDB is the top-level structure for the module. It contains configuration data about the
Module level code and pointers to configuration data about the device level codes.

directly. When the returned code is
was not able to carry the specified error code back to the application. Under those
circumstances, the proper error code is recorded in this element. The element is the first in the
structure so that the user can cast the CSMDB pointer into an INT4 pointer and retrieve the
local error (this eliminates the need to include the CSMDB template into the application
code).

value. For NSE, this should point to an array of
UINT1 with 32 or 12 elements for NSE-20G
and NSE-8G respectively.
