The chipset module initialization profiles provide the user with a convenient way of setting up
common setups in PMC device drivers. This appendix covers the CSD initialization in the context
of centralized TeleCombus and SBI336 bus operation. Example MIVs, DIVs and GIVs will be
presented for those system configurations and the code can be found in
example/nbcs_profile.c
and used in the target application code. Additional profiles may be created by the user for other
required applications.
For a detailed description of the module, device, and group initialization structures, please refer to
page 63 where the MIV, DIV, and GIV are defined. Also please refer to section 5.1 for a
description of the profile usage. Initialization profile management are described on page 104.
Centralized TeleCombus Application
All SBS and NSE devices are under the control of a single microprocessor. The OPA library is
also activated. SBS devices are passing TeleCombus traffic. Path termination mode is HPT.
Module Initialization Vector: nbcsInitMivCentralTelecombus
This profile can be used to set the system in centralized TeleCombus mode with a 1-stage time-
space-time fabric:

Bus type is TeleCombus
switching mode is column
Both SBS and NSE device drivers are present
standard fabric is assumed
standard OPA scheduling is selected
all connection map settings are automatically populated to the offline pages of the devices
all connection map page switching is controlled by software
all offline pages are automatically synchronized with the online connection page
all working/protect link selection in SBS devices are controlled by hardware pin
