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#,
S1_PAR, S1_PERR#, S1_SERR#, S1_FRAME#, S1_IRDY#, S1_TRDY#,
S1_LOCK#, S1_devsel#, S1_STOP#, S2_AD, S2_CBE#, S2_PAR, S2_PERR#,
S2_SERR#, S2_FRAME#, S2_IRDY#, S2_TRDY#, S2_LOCK#, S2_DEVSEL#,
and S2_STOP#.
4. REQ# signals have a setup of 10 and GNT# signals have a setup of 12.
