Moreover, following table describes the possible system clock configurations for each mode:

Following an example that describes how to manage module configuration

●

Current mode: Drun with system clock = IRC (default)

●

Target mode: RUN0 mode with system clock = XOSC

Steps

●

Configuration of RUNO mode

–

ME_RUN0_MC.OSCON = 1

–

ME_RUN0_MC.SYSCLK = XOSC

●

Transition request

–

ME_MCTL = DRUN + KEY

–

ME_MCTL = DRUN + INVERTED KEY

●

Waiting for the transition complete through the ME_IS.I_MTC bit
