This LSI has an on-chip clock pulse generator that generates the system clock (φ), the bus master
clock, and internal clocks. The clock pulse generator consists of an oscillator, duty adjustment
circuit, clock selection circuit, medium-speed clock divider, bus master clock selection circuit,
subclock oscillator, and wave formation circuit. A block diagram of the clock pulse generator is
shown in figure 23.1.
Frequency changes are performed by software by settings in the low-power control register
(LPWRCR) and system clock control register (SCKCR).
