(1) The supply voltage defined by OPP100 should be applied to this power domain before the device is released from reset.
(2) Not available on the ZCE package. VDD_MPU is merged with VDD_CORE on the ZCE package.
(3) This supply is sourced from an internal LDO when RTC_KALDO_ENn is low. If RTC_KALDO_ENn is high, this supply must be sourced
from an external power supply.
(4) VDDS should be supplied irrespective of 1.8-V or 3.3-V mode of operation of the dual-voltage IOs.
(5) For more details on power supply requirements, see Section 4.1.4.
(6) Not available on the ZCE package.
(7) This terminal is connected to analog circuits in the respective USB PHY. The circuit sources a known current while measuring the
voltage to determine if the terminal is connected to VSSA_USB with a resistance less than 10 Ω or greater than 100 kΩ. The terminal
should be connected to ground for USB host operation or open-circuit for USB peripheral operation, and should never be connected to
any external voltage source.
