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.

Defaults¶

No defaults. Implicitly defaults to n.
