correctly indicates its capability. The LSIFC929XL reports
0b10 in this eld to indicate that the designed maximum
memory read bytes count is 2048.
Device Complexity
20
The PCI function clears this read-only bit to indicate that
the LSIFC929XL is a simple device.
Unexpected Split Completion
19
The PCI function sets this read-only bit when it receives
an unexpected split completion. After this bit is set, this
bit remains set until software clears it. Write a one (1) to
this bit to clear it.
Split Completion Discarded
18
The PCI function sets this read-only bit when it discards
a split completion. After this bit is set, this bit remains set
until software clears it. Write a one (1) to this bit to clear it.
133 MHz Capable
17
The MA[8] power-on sense pin controls this read-only bit.
Allowing the internal pull-downs to pull MA[8] LOW sets
this bit and enables 133 MHz operation of the PCI bus.
Pulling MA[8] HIGH clears this bit and disables 133 MHz
operation of the PCI bus. Refer to Table 4.3 on page 4-10
for details on the power-on sense pins.
64-Bit Device
16
The MA[9] power-on sense pin controls this read-only bit.
Allowing the internal pull-downs to pull MA[9] LOW sets
this bit and indicates a 64-bit PCI Address/Data bus.
Pulling MA[9] HIGH clears this bit and indicates a 32-bit
PCI Address/Data bus. If using the LSIFC929XL on an
add-in card, this bit must indicate the size of the
PCI Address/Data bus on the card. Refer to Table 4.3 for
details on the power-on sense pins.
Bus Number
[15:8]
These read-only bits indicate the number of the
LSIFC929XL bus segment. This PCI function uses this
number as part of its Requester ID and Completer ID.
