A PCI-standard 32-bit read-only register mapped into the PCI configuration space in PCI mode or in mode 0 (DCTR[HM] = $1 or $0). CDID/CVID is accessed if a configuration read command is in progress and the PCI address is $00. The DID[15–0] bits identify the DSP. The VID[15–0] bits identify the manufacturer of the DSP. The contents of CDID/CVID are hardwired and are unaffected by any type of reset. The host processor can access CDID/CVID only when the HI32 is in PCI mode (DCTR[HM]≠$1).
