Clock oscillator circuitry (CPG: clock pulse generator) consists of an external oscillator, an on-
chip oscillator, a duty correction circuit, a clock select circuit, and system clock dividers.
Figure 5.1 shows a block diagram of the clock pulse generator.
The system clock ( ) is a basic clock on which the CPU and on-chip peripheral modules operate.
The system clock is divided into /2 to /8192 by prescaler S and the divided clocks are supplied
to respective peripheral modules.
