As shown in
timing diagram. The taps used in this wakeup sequence are generated based upon user configuration settings in the
SLP_CFG3 register.”
1. The duration of Power Good is 3 ILO Cycles.
2. The timing of T0 – T4 is based on the IMO frequency and the settings in the SLP_CFG3 register. For additional information, refer to the
