H8S/2456, H8S/2456R, H8S/2454 Group
This LSI has an on-chip clock pulse generator (CPG) that generates the system clock (
internal clocks. The clock pulse generator consists of an oscillator circuit, a system-clock PLL
circuit and a divider.
Figure 23.1 shows a block diagram of the clock pulse generator.
The frequency of the system clock from the oscillator can be changed by means of the system-
clock PLL circuit and divider. Frequency changes are made by software by means of settings in
the PLL control register (PLLCR).
The USB module requires a 48-MHz clock. Set the frequency of the USB dedicated clock (cku toe
48 MHz. Changes to the frequency of the USB dedicated clock are made by software by means of
settings in the USB PLL control register (USPLLCR).
