Section 5 Clock Pulse Generators
5.2
Figure 5.7 shows a block diagram of the subclock generator.
5.2.1
Clock pulses can be supplied to the subclock divider by connecting a 32.768-kHz crystal
resonator, as shown in figure 5.8. Figure 5.9 shows the equivalent circuit of the 32.768-kHz crystal
resonator.
