Interface/Clock Configuration
This block provides functions to configure the bus interface of the chipset and controls the
CSU/DLLs operation.
Configuring Bus Interface: nbcsIntfCfgBus
SBS devices in the chipset can either operate in SBI or TeleCombus mode. There are bus-related
parameters to configure in either of the bus modes. This function configures the bus mode and
various other aspects of the bus operating mode. In addition, the current state of the configuration
can be read back using this function. (Note: Interface configuration parameters belong to the SBS
devices only. NSE device operation does not change whether the chipset system is in SBI or
TeleCombus mode).
This function accepts group handle and configures the group of SBS with the same bus
configuration parameter given by
with a group handle in “get” mode. It is user’s responsibility to make sure the buffer is large
enough to hold the parameters returned for all members.
