8.3.6.9 Output Sequencing

Output sequencing can be triggered by hardware or software through ACT, SLEEP, RTC wake, FORCE_SHDN, NPWR_BTN (if enabled), NEM_PD (if enabled), and NRST_IN (if enabled).

Such events start sequencing the outputs (ENx and CLK32K) according to the settings in registers Table 8-27, Table 8-30, Table 8-31, Table 8-32, Table 8-33, and Table 8-34.

In those registers, Slot 1 is the earliest slot that can be selected and it indicates that the ENx (or CLK32K) will toggle in the first time slot after the triggering event. The example timing diagram in Figure 8-16 shows the time delays specified in Section 7.6 .
