Description
This register is reserved for AMCC’s S5920 silicon
revision identification number. The register defaults to
that value after power up. Write operations from the
PCI interface have no effect on the register. User-
defined values can be boot-loaded from an optional
external non-volatile. AMCC does not recommend
changing the register value. The Sub-system Vendor
ID and/or Subsystem ID are intended for end user
information.
