Clock Loss Interrupt Graceful Transition

Hello,

 

I am currently working on a set of custom boards with K60F120 micros. I have a few corner  cases in operation in which the "main" clock on OSC0 may be lost. I would like to enable the Clock Loss interrupt to gracefully transition to a different MCG state without resetting the device.

 

From which states can one successfully transition to in the interrupt? Also, when a clock loss occurs, how is the device clocked until a new source is selected? Unless I missed it, I did not see any of this documented in the K60 reference manual.

 

Thanks!
