(1) This pin must always be connected via a 1-µF capacitor to VSS.

(2) SDIO LDO is not used since 3.3V operation of MMC0/1 is not supported. Therefore, VDDA_1P8_SDIO, CAP_VDDA_1P8_SDIO,

CAP_VDDSHV_SDIO, and VDDA_3P3_SDIO must be connected to VSS.

(3) These power rails should be connected together on the board level.

(4) VDDA_POR_WKUP is preferred to be connected to CAP_VDDA_1P8_IOLDO_WKUP when using internal POR feature.

(5) The VDDA_VSYS_MON pin provides a way to monitor the system power supply and is not fail-safe, unless implemented with the

appropriate resistor voltage divider source. For more information, see Section 7.2.5, System Power Supply Monitor Design Guidelines.
