Table 6-5 and Figure 6-7
describes the device power-down sequencing.
Note: The power supply sequencing
requirements defined in this section does not include entry or exit from low power
modes. See Partial IO Power Sequencing for more information on the
requirements for entering or exiting from Partial IO low power mode.

(1) VDDSHV_CANUART, VDDSHV_MCU, and
VDDSHVx [x=0-3] when operating at 3.3V.
(2) VDDSHV_CANUART, VDDSHV_MCU, and
VDDSHVx [x=0-3] when operating at 1.8V.
(3) VDDSHV5, and VDDSHV6 were
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.
(4) VDD_CANUART when connected to an
always-on power source for Partial IO low power mode.
(5) VDD_CANUART, VDD_CORE,
VDDA_CORE_CSI_DSI, VDDA_CORE_DSI_CLK, VDDA_CORE_USB0, and VDDA_DDR_PLL0 when
operating at 0.75V
(6) VDD_CANUART, VDD_CORE,
VDDA_CORE_CSI_DSI, VDDA_CORE_DSI_CLK, VDDA_CORE_USB0, and VDDA_DDR_PLL0 when
operating at 0.85V
