Bit 15
Detected Parity Error.
Hardwired to zero. The ISA bridge does not check bus parity.
Signaled System Error.
This bit is set when ISA bridge asserts SERR# on PCI bus.
Received Master Abort Status.
This bit is set when the ISA bridge is target aborted as a master on the PCI bus.
Software sets this bit to 0 by writing a 1 to it.
Received Target Abort Status.
This bit is set when the ISA bridge target aborts a PCI transaction as a target.
Software sets this bit to 0 by writing a 1 to it.
Signaled Target Abort Status.
This bit is set when the ISA bridge signals a target abort for a PCI transaction.
Software sets this bit to 0 by writing a 1 to it.
DEVSEL# Timing.
This 2 bits always return a 01b(medium decode).
Data Parity Detected(Not supported).
Hardwired to zero.
Fast Back-to-Back(Not supported).
Hardwired to zero.
