Clock oscillator circuitry (CPG: clock pulse generator) is provided on-chip, including a system
clock pulse generator. The system clock pulse generator consists of a system clock oscillator, a
duty correction circuit, and system clock dividers.
Figure 5.1 shows a block diagram of the clock pulse generators.
The basic clock signals that drive the CPU and on-chip peripheral modules are ø.
The system clock is divided into ø/8192 to ø/2 by prescaler S and they are supplied to respective
peripheral modules.

Clock pulses can be supplied to the system clock divider either by connecting a crystal or ceramic
resonator, or by providing external clock input. Figure 5.2 shows a block diagram of the system
clock generator.
