19.1
The H8S/2350 Group has a built-in 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, a medium-
speed clock divider, and a bus master clock selection circuit.
