23.1
The H8S/2138 Group and H8S/2134 Group have an on-chip clock pulse generator (CPG) that
generates the system clock ( ), the bus master clock, and internal clocks.
The clock pulse generator consists of an oscillator circuit, a duty adjustment circuit, clock
selection circuit, medium-speed clock divider, bus master clock selection circuit, subclock input
circuit, and waveform shaping circuit.
