This LSI has an on-chip clock pulse generator that generates the system clock (φ) and internal
clocks. The clock pulse generator consists of an oscillator circuit and PLL circuit. Figure 15.1
shows a block diagram of the clock pulse generator.
The frequency can be multiplied by two by means of the PLL circuit.
15.1
Clock pulses can be supplied by connecting a crystal resonator, or by input of an external clock.
15.1.1
A crystal resonator can be connected as shown in the example in figure 15.2. Select the damping
resistance R
crystal resonator is used, the range of usable frequencies is from 5 to 16.5 MHz and a crystal
resonator with half frequency of the system clock (φ) should be used.
Figure 15.3 shows the equivalent circuit of the crystal resonator. Use a crystal resonator that has
the characteristics shown in table 15.2.
