1.
See Figure 17-1 PCI Signal Timing Measurement Conditions.
2.
All primary interface signals are synchronized to P_CLK. All secondary interface
signals are synchronized to either S1_CLKOUT or S2_CLKOUT.
3.
Point-to-point signals are P_REQ#, S1_REQ#[7:0], S2_REQ#[6:0], P_GNT#,
S1_GNT#[7:0], S2_GNT#[6:0], HSLED, HS_SW#, HS_EN, and ENUM#. Bused
signals are P_AD, P_BDE#, P_PAR, P_PERR#, P_SERR#, P_FRAME#, P_IRDY#,
P_TRDY#, P_LOCK#, P_DEVSEL#, P_STOP#, P_IDSEL, S1_AD, S1_CBE#,

and S2_STOP#.
4.
REQ# signals have a setup of 10 and GNT# signals have a setup of 12.
