Figure 9-2 depicts the power up sequencing order listed in Table 9-1. Notice EN1 rises at the same time as the ACT signal due to the number 1 slot selection. Additonally, notice EN3 and EN4 rise 625us after EN1 due to the number two slot selection. The TPS38700-Q1 timing tool found under the "Design tool's & simulation" section of the TPS38700-Q1 web page can be used to assist in implementing a desired slot selection.
