7.6.4 Example of setting X1 oscillation clock
oscillation clock. To subsequently change the clock to the X1 oscillation clock, set the oscillator and start oscillation by
using the operation speed mode control register (OSMC), clock operation mode control register (CMC), and clock
operation status control register (CSC) and wait for oscillation to stabilize by using the oscillation stabilization time counter
status register (OSTC). After the oscillation stabilizes, set the X1 oscillation clock to f
register (CKC).

Set address 000C1H to FBH.
[Register settings] Set the register in the order of <1> to <5> below.
<1> Use the OSMC register to set the frequency of the CPU/peripheral hardware.
<2> Set (1) the OSCSEL bit of the CMC register to operate the X1 oscillator.
<3> Clear (0) the MSTOP bit of the CSC register to start oscillating the X1 oscillator.
