PCI and Related Signals

The signals detailed in this sub-section use a “PCI” buffer

type except SUSP#, SUSPA#, and RESET_OUT# they use

types “Q3” and “Q7” respectively. For a detailed explana-

tion of buffer types, see Table 2-4 "Buffer Type Character-

istics" on page 28.

In this subsection, unless otherwise noted:

• All timing specifications are specified under the oper-

ating conditions listed in Table 6-3 on page 526 (i.e.,

VCORE and VCORE_VSB = All; VIO and VIO_VSB = All;

TCASE = All).

• Signals are referenced to PCI_CLK low-to-high edge.

• Signal and test parameters are defined in Figure 6-2

"AC Reference Timing and Test Definition" on page 530.
