CPG0400A_010020020100
This LSI has an on-chip clock pulse generator (CPG) that generates the system clock (φ) and
internal clocks.
The clock pulse generator consists of an oscillator circuit, PLL circuit, and divider.
Figure 22.1 shows a block diagram of the clock pulse generator.
The frequency can be changed by means of the PLL circuit. Frequency changes are made by
software by means of settings in the PLL control register (PLLCR) and the system clock control
register (SCKCR).
22.1
The clock pulse generator has the following registers.
• System clock control register (SCKCR)
• PLL control register (PLLCR)
