20.1
The chip has an on-chip clock pulse generator (CPG) that generates the system clock (φ), 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.
In the chip, the CPG has a medium-speed mode in which the bus master runs on a medium-speed
clock and the other supporting modules run on the high-speed clock, and a function that allows the
medium-speed mode to be disabled and the clock division ratio to be changed for the entire chip.
A clock from φ/2 to φ/32 can be selected.

Figure 20.1 shows a block diagram of the clock pulse generator.
