Each Dual-voltage IO domain (VDDSHVx [x=0-5] and VDDSHV_MCU) provides power supply to a fixed set of IOs (peripherals). 3.3 V or 1.8 V supply voltage can be connected to each of the Dual-voltage IO domains. For all the Dual-voltage IO domains except VDDSHV5, it is recommended to connect the required supply voltage during power-up.
VDDSHV5 has been designed to support power-up, power-down, or dynamic supply voltage change without any dependency on other supplies. This capability is required to support UHS-I SD Cards.
