21.3
The duty adjustment circuit is valid when oscillation frequency is more than 5 MHz. The duty
adjustment circuit adjusts clock output fr/m the system clock oscillator to generate the system
clock (φ).
21.4
The medium-speed clock divider divides the system clock to generate φ/2, φ/4, φ/8, φ/16, and
φ/32.
21.5
The bus master clock selection circuit selects the clock supplied to the bus master by setting the
bits SCK2 to SCK0 in SCKCR. The bus master clock can be selected from system clock (φ), or
medium-speed clocks (φ/2, φ/4, φ/8, φ/16, φ/32).
