not be changed within the same instruction that changes the CLE bit contents).
482
A signal with the clock output frequency selected by bits FS0 to FS2 is selected by selector 1 and output.
The output signal has the same level as the LV bit when the CLE bit is cleared (0), and is output from the clock signal
When the CLE bit is cleared (0), the contents of the LV bit are output in synchronization with the clock signal, and further
Setting of bits FS0 to FS2 and the LV bit should only be performed when CLE = 0 (bits FS0 to FS2 and the LV bit should
