Clock oscillator circuitry (CPG: clock pulse generator) is provided on-chip, including both a
system clock pulse generator and a subclock pulse generator. The system clock pulse generator
consists of a system clock oscillator, a duty correction circuit, and system clock dividers. The
subclock pulse generator consists of a subclock oscillator circuit and a subclock divider.
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 and
system clock is divided by prescaler S to become a clock signal from /8192 to /2, and the
subclock is divided by prescaler W to become a clock signal from w/128 to w/8. Both the
system clock and subclock signals are provided to the on-chip peripheral modules.
