Each Dual-voltage IO domain (VDDSHVx [x = 0..3, 5..6], VDDSHV_MCU and VDDSHV_CANUART) 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.
VDDSHV5 and VDDSHV6 have been designed to support power-up, power-down, or dynamic voltage change without any dependency on other power rails. This capability is required to support UHS-I SD Cards.
Note the output buffer type available for the processor IOs (SDIO or LVCMOS) connected to the IO supply rails.
