Description
Defines the upper 16-bits of a 32-bit top address of an address range
for the bridge to determine when to forward I/O transactions from
one interface to the other.
Reset to 0
Description
Enhanced capabilities port offset pointer. Read as DCh to indicate
that the first item resides at that configuration offset.
Description
For POST to program to FFh, indicating that the PI7C8150A does not
implement an interrupt pin.
Description
Interrupt pin not supported on the PI7C8150A
Description
Controls the bridge’s response to parity errors on the secondary
interface.
0: ignore address and data parity errors on the secondary interface
1: enable parity error reporting and detection on the secondary
interface
Reset to 0
Controls the forwarding of S_SERR_L to the primary interface.
0: disable the forwarding of S_SERR_L to primary interface
1: enable the forwarding of S_SERR_L to primary interface
