GC5316 Board Diagnostics

The GC5316 contains built-in test features that can be used to confirm that the chip is operating correctly and to help

users debug their boards and systems that conatin the GC5316.

The diagnositc and board test procedures can be download from the web at www.ti.com as the GC5316 Diagnostics

Designer’s Kit.

GC5316 Programming

The cmd5016 program, its user’s guide, and example configuration files can be downloaded from the web at

www.ti.com as the GC5316 Configuration Designer’s Kit.

The GC5316 contains over 7,000 control and coefficient registers that must be written to in order to fully configure

the chip. Rather than program each of these registers individually, Texas Instruments supplies a configuration

program called cmd5316 which accepts top-level configuration information for the chip and then generates the full

The configuration controls have been defined in the functional description of each section of the chip. The following

tables summarize these controls and identify which register and which bits within the registers they occupy.

Each control register table has a column identifying whether the variable must be specified by the user in cmd5316

(U), is typically left at the default value and does not need to be specified (D), is computed by cmd5316 and should

not be set (C), or is for expert use only (E).

Tables are also included that show the top level page mapping for the chip controls, the status and measurement

result registers, and additional controls that are used with the GC101/GC5316 DIMM evaluation platform.
