DESCRIPTION
0: Secondary discard timer counts 215 PCI clock cycles
1: Secondary discard timer counts 210 PCI clock cycles
REVERSE BRIDGE – Bit is RO and ignored by PI7C9X110
Reset to 0
Bit is set when the discard timer expires and a delayed completion is
discarded at the PCI interface for the forward or reverse bridge
Reset to 0
Bit is set to enable to generate ERR_NONFATAL or ERR_FATAL for
forward bridge, or assert SERR_L for reverse bridge as a result of the
expiration of the discard timer.

DESCRIPTION
These bits apply to forward bridge only.
For initialization code to program to tell which input of the interrupt
controller the bridge’s INTA_L in connected to.
Reset to 00000000
DESCRIPTION
These bits apply to forward bridge only.
00000001: Designates interrupt pin INTA_L is used
Reset to 00h when reverse mode or 01h when forward mode.
DESCRIPTION
This register is valid only in forward bridge mode. It specifies how long of a
burst period that PI7C9X110 needs on the secondary bus in the units of ¼
microseconds.
