Table 19.4 External Clock Input Conditions when Duty Adjustment Circuit Is not Used
19.3
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 (φ).
19.4
The medium-speed clock divider divides the system clock to generate φ/2, φ/4, φ/8, φ/16, and φ/32.
19.5
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 high-speed mode, or
medium-speed clocks (φ/2, φ/4, φ/8, φ/16, φ/32).
