CONFIG_RAM_POWER_DOWN_LIBRARY

Enable API for turning off unused RAM segments

Type: bool

Help

This allows application to call API for disabling unused RAM segments
in the System ON mode. Effectively the application looses possibility
to use disabled portion of RAM.
This is usually not needed, but can improve battery lifetime for
applications that spend most of the time in the sleep mode with most
peripherals disabled.
