when using internal High-speed CR as clock source and multiplier to high frequency (for example 80MHZ or 96MHZ).

if the clock frequency need to be switched during the running of program, for exmaple, from 80MHZ change to 96MHZ.

firstly please change to high-speed CR from 80MHZ, and then change to 96MHZ from High-speed CR.
