HOLT INTEGRATED CIRCUITS

After selecting the Holt card, select the LCR button (top left) to see the Main Control Registers. Changes
to the LB configuration can be dynamically changed by entering new values from this menu. Alternately,
press the EEPROM button to see the 9056 EEPROM values shown below. Notice the Vendor ID is 10B5.
This is PLX’s vendor ID and must be used with the sub-ID 3566 that is assigned to Holt. A new end
product would require a unique Vendor ID from PCI-SIG (obtained by becoming a PCI-SIG member) or a
sub-ID obtained from PLX. For detailed information on these parameters and the PLX API’s refer to the
PLX SDK user’s guide and data sheet on the PEX8311. For the Holt card, there is no need to alter any of
these values.
On the bottom of the PlxMon screen is a console window where a menu of commands allow reading
and writing to LB memory spaces. These are useful during initial hardware checkout to confirm LB
configurations. Pressing “?” followed by a Return in this window lists a Help page of the commands. The
commands are also documented in the PLX API user manual and some examples are provided in the PLX
PEX8311 RDK Hardware Reference Manual.
