Section 5 Clock Pulse Generator
5.6.1
Clock pulses can be supplied to the subclock divider by connecting a 32.768-kHz crystal
resonator, as shown in figure 5.16. Figure 5.17 shows the equivalent circuit of the 32.768-kHz
crystal resonator.
5.6.2
When the subclock is not used, connect pin X1 to VCL or VSS and leave pin X2 open, as shown
in figure 5.18.
