LPM: Low power modes may inadvertently corrupt DDR contents

Details:

During entry to the Deep Sleep or RTC+IO+DDR low-power modes, the device may not properly transition the attached DDR into retention mode, which will lead to corruption of the DDR data.

Affected devices should not utilize these low power modes without applying the software workaround.

Workaround(s):

A workaround to this issue is provided in SDK versions 11.1 and later. The workaround ensures that an internal retention latch which controls DDR self-refresh is in the correct state through various reset scenarios.
