* Ensure these registers are written by the configuration EEPROM.
Most of these registers simply hold values which are presented in read-only registers in PCI
configuration space (see section 3.3).
PMDS(3:0) and PMDS(7:4) contain eight 2-bits, packed as shown below, returned as a value for bits
14:13 in PMCSR when PMCSR [12:9] = n where n references PMDSn (see section 3.3).
