18. Clock Pulse Generator
18.2
Clock pulses can be supplied by connecting a crystal resonator, or by input of an external clock
signal.
18.2.1
Circuit Configuration: A crystal resonator can be connected as in the example in figure 18.2.
The damping resistance Rd should be selected according to table 18.1. An AT-cut parallel-
resonance crystal should be used.

Note: A crystal resonator between 2 MHz and 20 MHz can be used. If the chip is to be operated
Crystal Resonator: Figure 18.3 shows an equivalent circuit of the crystal resonator. The crystal
resonator should have the characteristics listed in table 18.2.

at less than 2 MHz, the on-chip frequency divider should be used. (A crystal resonator of
less than 2 MHz cannot be used.)
