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.
In the H8/38124 Group, the system clock pulse generator includes an on-chip oscillator.
4.1.1
Figure 4.1 shows a block diagram of the clock pulse generators of the H8/38024, H8/38024S, and
H8/38024R Group. Figure 4.2 shows a block diagram of the clock pulse generators of the
H8/38124 Group.
