SYSOSC Module
Functional
MFCLK fails to start up in certain conditions.
MFCLK will not start to toggle in the below scenario:
1. FCL mode is enabled and then MFCLK is enabled
2. Enter a low power mode where SYSOSC is disabled (SLEEP2/STOP2/STANDBY0/STANBY1).
3. Now asynchronous clock request is received from some peripheral which uses MFCLK as its functional clock.
Avoid the above scenario - check that your system does not use FCL and MFCLK along with the listed low power modes while asynchronous fast clock requests are enabled.
