While changing from one mode to another, the MCG module needs to wait some clock cycles for the clock mode to set in (as given in the Reference manual).What I want to know what number of cycles do we need to wait? I cant exactly use an endless while loop. I want to have a back up resort which would reset the module and re-call that function for changing the mode in MCG. But for that, I need a number (number of clock cycles to wait) and the rationale behind it. For OSC module, the reference manual has given the wait time of 4096 clock cycles but no such thing for MCG.
