The 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 a system clock divider. The subclock pulse generator consists of an
on-chip oscillator, division ratio setting register, and a sub-clock 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 system clocks (
and subclocks (
ratio setting register (ROPCR) for the on-chip clock pulse generator can be used as one of the
input clocks for the watchdog timer.
