The processor includes one integrated SDIO LDO to support SD card IO voltage switching. An output capacitor must be connected close to the LDO output pin.
Only one MMCSD port (selectable through V1P8_SIGNAL_ENA bit) can be connected to the SDIO LDO in a given system.
VDDSHV5 was designed to support power-up, power-down, or dynamic voltage change without any dependency on other power rails.
For more details, refer the Integrated Low-dropout Regulator (LDO) section in the Power chapter of the device-specific TRM.
