This LSI has an on-chip clock pulse generator (CPG) that generates the system clock (φ) and
peripheral clock (Pφ) to generate the internal clock (φ/2 to φ/8192, Pφ/2 to Pφ/1024). The CPG
consists of an oscillator, PLL circuit, and pre-scaler. A block diagram of the clock pulse generator
is shown in figure 4.1. The frequency from the oscillator can be modified by the PLL circuit.
