1. Connecting a 76.8-kHz/160-kHz crystal oscillator
Clock pulses can be supplied to the subclock divider by connecting a 76.8-kHz/160-kHz crystal
oscillator, as shown in figure 4-7. Follow the same precautions as noted under 3. notes on board
design for the system clock in 4.2.
Figure 4-8 shows the equivalent circuit of the 76.8-kHz/160-kHz crystal oscillator.
2. Pin connection when not using subclock
When the subclock is not used, connect pin DX
figure 4-9.
