The wording of the I
Currently incorrect:
Must be changed to the following:
PCI/X initialization sequence
The frequency tolerances listed in Table 46 in the Intel
Developer’s Manual (Section 3.11.1) are misleading, resulting in an incorrect PCI/X CAP#[1,0]
selection for the desired initialization sequence. For example, Px_RSTDIR = 1 and PCI/X
CAP#[1,1] cause the PCI-X 133 MHz initialization sequence to be driven by the 80314. Thus, a
device expecting 100 MHz operation with PCI/X CAP#[1,1] receives the incorrect initialization
sequence (PCI/X 133).
The proper PCI/X CAP# selection for 100 MHz PCI/X operation is PCI/X CAP#[1,0]. Note that
external clocking is recommended for 100 MHz PCI/X operation since the PCI/X CAP#[1,0]
setting causes the 80314 to drive its Px_CLK_OUT at SFN_CLK/2.
A new heading, “PCI/X Init. Pattern”, must be added to Table 46 to aid in proper PCI/X CAP#
selection:
PCI/X CAP#[0,1] Encoding When Px_RSTDIR = 1

NOTE:
† When the PCI/X CAP value is 10b, the Intel
PCI/X CAP#[1]
C capability wording
drives the SFN_CLK divided by two.
