Description
Master Abort Receive ASMI. Allow reception of a PCI bus master abort to be reported
in the TARE bit (MSR 50002002h[17]).
0: Disable.
1: Enable.
Busy Sustain. Controls the sustain time for keeping the clocks running after the internal
busy signals indicate that the clocks may be gated.
000: No sustain
001: 4 clock cycles
010: 8 clock cycles
011: 16 clock cycles
In-Bound Read Flush Timeout. Controls the flushing of in-bound prefetch read data.
When an in-bound read has completed on the PCI bus, an internal counter is loaded with
a value derived from this field. It then counts down on each PCI clock edge. When the
counter reaches 0, any remaining prefetched data is flushed. The counter stops counting
down if a subsequent in-bound read is received. It continues to count down through an
in-bound write and through any out-bound traffic.
000: 4 PCI clock edge
001: 8 PCI clock edges
010: 16 PCI clock edges
011: 32 PCI clock edges
In-Bound Read Flush Control. Controls the policy for discarding stale data from in-
bound read data FIFO.
00: Discard at end of in-bound read PCI transaction.
01: Discard upon timeout.
10: Discard at start of out-bound write or upon timeout.
11: Discard at start of out-bound write, at start of out-bound read or upon timeout.
In addition to these policies, in-bound read data will be discarded whenever a non-contig-
uous in-bound read is accepted, or when an in-bound write is received that will affect the
prefetched memory.
I/O Delay. Delay completion of out-bound I/O transactions for a configurable number of
PCI clock cycles.
000: 0 PCI clock cycles
001: 1 PCI clock cycles
010: 2 PCI clock cycles
011: 4 PCI clock cycles
100: 8 PCI clock cycles
101: 16 PCI clock cycles
110: 32 PCI clock cycles
111: 64 PCI clock cycles
Short Timer. When cleared to 0, delayed transactions are discarded after 2
cycles. When set to 1, delayed transactions are discarded after 2
normal operation. this bit should be cleared.
Early Read. When cleared to 0, out-bound reads are stalled until there is enough FIFO
space in the out-bound read FIFO to hold data for the entire transaction. When set to 1,
out-bound reads will start as soon as possible.
Read Hints Enable. When cleared to 0, all out-bound reads use PCI CMD = 6. When set
to 1, the PCI CMD provides a hint about the size of the read request.
6: 1, 2 or 4 DWORDs
E: 8 DWORDs
