Field Description
If this bit written during clock switching, it should be read back and confirmed before proceeding.
0 System OSC is disabled
1 System OSC is enabled
18.3.8 System OSC Divide Register (SCG_SOSCDIV)
The SCG_SOSCDIV register provides the control of 2 clock trees which can be used to
provide optional peripheral functional clocks, or alternative module clocks. Each clock
tree has optional dividers of the input SOSC clock. Changes to SOSCDIV should be done
when System OSC is disabled to prevent glitches to output divided clock.
Address: 4006_4000h base + 104h offset = 4006_4104h
