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,
system clock divider, and on-chip oscillator. The subclock pulse generator consists of a subclock
oscillator, on-chip oscillator clock divider, and subclock divider. Figure 4.1 shows a block
diagram of the clock pulse generators.
The reference clock signals that drive the CPU and on-chip peripheral modules are φ and φ
system clock is divided by prescaler S to become a clock signal from φ/8192 to φ/2. φ
