4.2
Clock pulses can be supplied to the system clock divider either by connecting a crystal or ceramic
oscillator, or by providing external clock input.
1. Connecting a crystal oscillator
Figure 4-2 shows a typical method of connecting a crystal oscillator.
Figure 4-3 shows the equivalent circuit of a crystal oscillator. An oscillator having the
characteristics given in table 4-1 should be used.
