This is the operating clock for the CPU and watchdog timer.
The clock source for the CPU clock can be chosen to be the main clock, sub clock, on-chip oscillator clock
or the PLL clock.
If the main clock or on-chip oscillator clock is selected as the clock source for the CPU clock, the selected
clock source can be divided by 1 (undivided), 2, 4, 8 or 16 to produce the CPU clock. Use the CM06 bit in
CM0 register and the CM17 to CM16 bits in CM1 register to select the divide-by-n value.
When the PLL clock is selected as the clock source for the CPU clock, the CM06 bit should be set to “0”
and the CM17 and CM16 bits to “00
After reset, the on-chip oscillator clock divided by 16 provides the CPU clock.
Note that when entering stop mode from high or middle speed mode, on-chip oscillator mode or on-chip
oscillator low power dissipation mode, or when the CM05 bit in the CM0 register is set to “1” (main clock
turned off) in low-speed mode, the CM06 bit in the CM0 register is set to “1” (divide-by-8 mode).
These are operating clocks for the peripheral functions.
Of these, fi (i = 1, 2, 8, 32) and fi

Additionally, the f1 and f2 clocks are also used for dead time timer.
