19.2
Clock pulses can be supplied by connecting a crystal resonator, or by input of an external clock.
19.2.1
A crystal resonator can be connected as shown in the example in figure 19.2. Select the damping
resistance R
Table 19.1 Damping Resistance Value
Figure 19.3 shows the equivalent circuit of the crystal resonator. Use a crystal resonator that has
the characteristics shown in table 19.2.
