The CDID/CVID is a PCI standard 32-bit read-only register mapped into the PCI
configuration space, when in the PCI mode or in mode 0 (HM=$1 or $0). CDID/CVID is
accessed if a configuration read command is in progress and the PCI address is $00.
The DID15-DID0 bits identify the DSP. The VID15-VID0 bits identify the manufacturer
of the DSP. The contents of CDID/CVID are hardwired and cannot be affected by any
type of reset.
The CDID/CVID cannot be accessed by the host when not in the PCI mode (HM≠$1).
