4.1
Clock pulses can be supplied from a connected crystal resonator or an external clock.
4.1.1
Circuit Configuration: A crystal resonator can be connected as shown in figure 4.2. Use the
damping resistance (Rd) listed in table 4.1. Use an AT-cut parallel-resonance type crystal
resonator that has a resonance frequency of 4 to 12.5 MHz. It is recommended to consult crystal
dealer concerning the compatibility of the crystal resonator and the LSI.
Table 4.1
Crystal Resonator: Figure 4.3 shows an equivalent circuit of the crystal resonator. Use a crystal
resonator with the characteristics listed in table 4.2.
