Section 6 Clock Pulse Generators

6.1 Overview

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, system clock divider, and a clock divider (prescaler S) for the

on-chip peripheral modules. The subclock pulse generator consists of a subclock oscillator

circuit, subclock divider, and a further subclock divider (prescaler W) for time-base use.
