6.3.8 TO_ACTIVE

When a trigger causes the TO_ACTIVE sequence to execute, all rails of the PMICs power up in the recommended processor power up sequence as shown in Figure 6-11.

At the beginning of the TO_ACTIVE sequence both PMICs clear SPMI_LP_EN and LPM_EN and set AMUXOUT_EN and CLKMON_EN.

Note: BUCK3 Monitor, mVDDS_DDR_X, monitors the external regulator controlled by GPIO3, EN_DDR_BUCK. Although these occur at the same time, the analog BIST, which first checks the actual voltage being monitored, occurs approximately 3.7 ms after the monitor is enabled. This is a function of the voltage and slew rate of BUCK3 as described in Table 5-3.
