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, PLL circuit, clock
selection circuit, medium-speed clock divider, and bus master clock selection circuit. A block
diagram of the clock pulse generator is shown in figure 19.1.
The frequency can be changed by means of the PLL circuit. Frequency changes are performed by
software by settings in the low-power control register (LPWRCR) and system clock control
register (SCKCR).
