4.1
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 and system clock dividers. The subclock pulse generator
consists of a subclock oscillator circuit and a subclock divider.
4.1.1
Figure 4.1 shows a block diagram of the clock pulse generators.
4.1.2
The basic clock signals that drive the CPU and on-chip peripheral modules are and
the clock signals have names: is the system clock,
