Remarks 1.

Calling this API function changes the clock/buzzer output controller to reset status.
For this reason, writes to the control registers after this API function is called are ignored.

Remarks 2.

This API function stops the clock supply to the clock/buzzer output controller, by operating the RTCEN bit of peripheral enable register n.
For this reason, this API function also stops the clock supply to other peripheral devices sharing the RTCEN bit (e.g. real-time clock).
