Registers Description
4 16 Port 0 Fault Register
10 22 Port 1 Fault Register
Bit 8: No device plugged into a configured port
Bit 9: Bad ID code: device other than a rail plugged into the
port
Bit 10: Bad rail communication check bits received
Bit 11: PMI interface is not ready
5 17 Port 0 Check Bit Fault Counter Register
11 23 Port 1 Check Bit Fault Counter Register
These registers can be reset by setting bit 9 of the Drive
Control register (100/1100)
