19.1
The H8/3024 Group has a built-in clock pulse generator (CPG) that generates the system clock ( )
and other internal clock signals ( /2 to /4096). After duty adjustment, a frequency divider divides
the clock frequency to generate the system clock ( ). The system clock is output at the pin *
furnished as a master clock to prescalers that supply clock signals to the on-chip supporting
modules. Frequency division ratios of 1/1, 1/2, 1/4, and 1/8 can be selected for the frequency
divider by settings in a division control register (DIVCR) *
reduced in almost direct proportion to the frequency division ratio.
Notes: 1. Usage of the pin differs depending on the chip operating mode and the PSTOP bit
2. The division ratio of the frequency divider can be changed dynamically during

setting in the module standby control register (MSTCR). For details, see section 20.7,

operation. The clock output at the pin also changes when the division ratio is
changed. The frequency output at the pin is shown below.
