19.2
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 (φ).
19.3
The medium-speed clock divider divides the system clock (φ), and generates φ/2, φ/4, φ/8, φ/16,
and φ/32 clocks.
19.4
The bus master clock select circuit selects a clock to supply the bus master with either the system
clock (φ) or medium-speed clock (φ/2, φ/4, φ/8, φ/16, or φ/32) by the SCK2 to SCK0 bits in
SBYCR.
