9.2.2.7 Clock, Reset, and Miscellaneous
The PWRCTL_POL is left unconnected which results in active-high power enable (PWRCTL1, PWRCTL2,
PWRCTL3, and PWRCTL4) for a USB VBUS power switch. The 1-µF capacitor on the GRSTN pin can only be
used if the VDD11 supply is stable before the VDD33 supply. Depending on the supply ramp of the two supplies,
the user may need to adjust the capacitor.
