25.2
The duty correction circuit is valid when the oscillating frequency is 5 MHz or more. It corrects
the duty of a clock that is output from the oscillator, and generates the system clock (ø).
25.3
The medium-speed clock divider divides the system clock (ø), and generates ø/2, ø/4, ø/8, ø/16,
and ø/32 clocks.
