Description
Reserved
These bits are always read as 0. The write value
should always be 0.
66MHz-Operation Capable Status
Indicates whether the PCIC can operate at 66MHz.
0: PCIC operates at 33 MHz
1: PCIC operates at 66 MHz
PCI Power Management (extended function)
Indicates whether the PCI power management is
supported.
0: Power management not supported
1: Power management supported
Reserved
These bits are always read as 0. The write value
should always be 0.
