PCI Master IDE Device
Specifies the PCI master IDE device.
0: PCI slave IDE device
1: PCI master IDE device
If this bit is written during register initialization
(PCICR.CFINT = 0) in the PCIC, the value of this bit is
updated. The value is not updated after initialization
(PCICR.CFINT = 1).

Reserved
These bits are always read as 0. The write value
should always be 0.

PCI Programmable Indicator (Secondary)
If this bit is written during register initialization
(PCICR.CFINT = 0) in the PCIC, the value of this bit is
updated. The value is not updated after initialization
(PCICR.CFINT = 1).

PCI Operating Mode (Secondary)
If this bit is written during register initialization
(PCICR.CFINT = 0) in the PCIC, the value of this bit is
updated. The value is not updated after initialization
(PCICR.CFINT = 1).
1 PIP 0 SH: R/W
PCI: R
PCI Programmable Indicator (Primary)
If this bit is written during register initialization
(PCICR.CFINT = 0) in the PCIC, the value of this bit is
updated. The value is not updated after initialization
(PCICR.CFINT = 1).
