Description
Holds the maximum number of PCI clocks that PI7C7300D will wait
for initiator to retry the same cycle before reporting timeout. Master
timeout occurs after 2
Default is 400h.
Description
Holds the maximum number of attempts that PI7C7300D will try
before reporting retry timeout. Retry count set at 2
Default is 0100 0000h.
Description
Sets the duration (in PCI clocks) during which PI7C7300D will
record the number of successful transactions for performance
evaluation. The recording will start right after this register is
programmed and will be cleared after the timer expires. Maximum
period is 128 seconds at 33MHz.
Reset to 0.
Description
Stores the successful I/O read count on S1 or S2 and is updated when
the sampling timer is active.
