The table below describes the device power-down sequencing.
- VDDSHV_MCU and VDDSHVx [x=0-5] when operating at 3.3V.
- VDDSHV_MCU and VDDSHVx [x=0-5] when operating at 1.8V.
- VDDSHV5 was 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.
- VDD_CORE and VDDR_CORE are expected to be powered by the same source so the voltages ramp together.
