18.4
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 ( ).
18.5
The medium-speed clock divider divides the system clock to generate /2, /4, /8, /16, and /32.
18.6
The bus master clock selection circuit selects the system clock ( ) or one of the medium-speed
clocks ( /2, /4, or /8, /16, and /32) to be supplied to the bus master, according to the settings
of the SCK2 to SCK0 bits in SCKCR.
