2.1.1 GPIO Output Configuration in Deep Sleep and Extreme Deep Sleep

In the Deep Sleep and Extreme Deep Sleep modes, GPIO must not be set to the output state of pin HIGH.

Configuring the GPIO state to pin High during the Deep Sleep and Extreme Deep Sleep modes will cause leakage current and potential reliability issues on the silicon.

This issue is only applicable when the CPU is in the Deep Sleep/Extreme Deep Sleep mode and when GPIO is configured as the output state pin HIGH.

Work Around:

Set the state of GPIOs to low before entering DS/XDS for the least current consumption, either by output state or by pull-down.

Note:

The work around is working in A2 and newer versions.
