The CCCR/CRID 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). CCCR/CRID is
accessed if a configuration read command is in progress and the PCI address is $08.
The RID7-RID0 bits specify the DSP specific identifier (as an extension of Device ID).
The CCCR/CRID cannot be accessed by the host when not in the PCI mode (HM≠$1)
The contents of CCCR/CRID are hardwired and not affected by any type of reset.
