Document #: 38-07118 Rev. *A
10. All outputs loaded as per Table 3, see Figure 2.
12. Probes are placed on the pins, and measurements are acquired at 1.5V for 3.3V signals and at crossing points for CPU clocks (see Figure 3).
13. This measurement is applicable with Spread ON or Spread OFF.
14. Probes are placed on the pins, and measurements are acquired at 2.4V (see Figure 3).
15. Probes are placed on the pins, and measurements are acquired at 0.4V. (seeFigure 3).
16. As this function is available through SEL(0,1), therefore, the time specified is guaranteed by design.
17. Determined as a fraction of 2*(Trp-Trn) / (Trp+Trn) where Trp is a rising edge and Trn is an intersecting falling edge.
11. Probes are placed on the pins, and measurements are acquired between 0.4V and 2.4V for 3.3V signals and at 20% and 80% for CPU[(0:7), (0:7)#] signals
