CHAPTER 3 CLOCK CONTROLLER
3.2 Oscillation Stabilization Wait Time
■ Order of Priority for Oscillation Stabilization Wait Times
When multiple clocks are enabled simultaneously, the clock controller counts the respective
oscillation stabilization wait times of clocks according to a designated order of priority. Below
are the respective orders of priority for counting different oscillation stabilization wait times in
different clock modes.
•
Main clock mode
Sub-CR clock > Subclock > Main CR clock > Main CR PLL clock
•
Main CR clock mode
Sub-CR clock > Subclock > Main CR PLL clock > Main clock
•
Main CR PLL clock mode
Sub-CR clock > Subclock > Main clock
•
Subclock mode
Sub-CR clock > Main CR clock or main clock > Main CR PLL clock
•
