22
RW
PrivateDeviceMask6
0
Rerouting disabled for device 6.
1
Block assertion of S_AD(pin 22) for configuration transactions to device 6, assert S_AD(pin 31)
instead.
21
RW
PrivateDeviceMask5
0
Rerouting disabled for device 5.
1
Block assertion of S_AD(pin 21) for configuration transactions to device 5, assert S_AD(pin 31)
instead.
20
RW
PrivateDeviceMask4
0
Rerouting disabled for device 4.
1
Block assertion of S_AD(pin 20) for configuration transactions to device 4, assert S_AD(pin 31)
instead.

RW
Reserved
Masking for devices 3 and 2 is not implemented. Operation of the IBM 133 PCI-X Bridge R2.0 is unaffected by
the value of these bits.
17
RW
PrivateDeviceMask1
0
Rerouting disabled for device 1.
1
Block assertion of S_AD(pin 17) for configuration transactions to device 1, assert S_AD(pin 31)
instead.
16:0
RW
Reserved.
Operation of the IBM 133 PCI-X Bridge R2.0 is unaffected by the value of these bits.
