5.6.3 Example of setting X1 oscillator
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
clock control register (CKC).

CLS bit is not provided in the 78K0R/IB3. In the 78K0R/IB3, bit 7 is fixed to 0.
FSEL bit: Set this bit to 0 if the CPU/peripheral hardware clock is 10 MHz or less.
AMPH bit: Set this bit to 0 if the X1 oscillation clock is 10 MHz or less.
