NOTES:
1.
This delay is typically created from an RC circuit.
2.
The oscillator startup times are component and design specific. A crystal oscillator can take several 
second to reach a large enough voltage swing. A silicon oscillator can have startups times <10 ms.

G3 to S0
The timings shown in 
 
occur when a board event such as AC power is applied 
or power management controller (PMIC) power button is pressed. The following occurs:
1. Suspend (SUS/Always On) wells ramp in the order shown.
2. The external power management controller de-asserts PMC_RSMRST# after the 
suspend rails become stable.
3. PMC_SUSCLK will begin toggling after the de-assertion of PMC_RSMRST#.
4. The system is now in S4/S5 state. Depending on policy bits 
(GEN_PMCON1.PWR_FLR & GEN_PMCON1.AG3E), the SoC either waits for a wake 
event to transition to S0 or continues to S0 state automatically.
5. The transition from S4/S5 to S0 is initiated.
6. The SoC de-asserts PMC_SLP_S4#, and the DRAM (VDD/Un-switched) well ramps.
7. After the DRAM power rail ramp, the external power management controller drives 
DRAM_VDD_S4_PWROK high.
8. The SoC de-asserts PMC_SLP_S3#, and the Core (S0/Switched On) wells ramp in 
the order shown.
9. After all of Core power rails are stable, external power management controller 
drives PMC_CORE_PWROK and DRAM_CORE_PWROK to HIGH, the SoC will then
