1. See Figure 16-1 PCI Signal Timing Measurement Conditions.
2. All primary interface signals are synchronized to P_CLK. All secondary interface signals are synchronized to S_CLKOUT.
3. Point-to-point signals are p_req#, s1_req#<7:0>, s2_req#<7:0>, p_gnt#, s1_gnt#<7:0>, and s2_gnt#<7:0>. Bused signals
are p_ad, p_cbe#, 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#,
s3_par, s2_perr#, s2_serr#, s2_frame#, s2_irdy#, s2_trdy#, s2_lock#, s2_devsel#, and s2_stop#.
