6.12.2.2.3 Partial IO Power Sequencing

This section describes power supply sequence requirements when entering or exiting low power modes.

For more information on low power modes supported by this device and the names assigned to each low power

mode, see the Power Modes section in the Device Configuration chapter of the Technical Reference Manual.

Partial IO is the only low power mode that requires power supply changes to the device power rails. All power

supply rails except VDD_CANUART and VDDSHV_CANUART are turned off when operating in Partial IO mode.

The power sequence required to enter Partial IO is the same sequence defined in Section 6.12.2.2.2, Power-

Down Sequencing with the exception of VDD_CANUART and VDDSHV_CANUART, which remain powered.

The power sequence required to exit Partial IO is the same sequence defined in Section 6.12.2.2.1, Power-Up

Sequencing with the exception of VDD_CANUART and VDDSHV_CANUART, which are already powered.
