16.3 Duty Adjustment Circuit
When the oscillator frequency is 5 MHz or higher, the duty adjustment circuit adjusts the duty
cycle of the clock signal from the oscillator to generate the system clock (ø).
16.4 Prescalers
The prescalers divide the system clock (ø) to generate internal clocks (ø/2 to ø/4096).
