19.6.1
supply a clock to the subclock divider, connect a 32.768-kHz crystal resonator, as shown in figure
19.6. Figure 19.7 shows the equivalence circuit for a 32.768-kHz oscillator.
19.6.2
If no subclock is required, connect the OSC1 pin to Vss and leave OSC2 open, as shown in figure
19.8. Set the SUBSTP bit of LPWRCR to 1. If this setting is not made, transition to power-down
mode may not complete properly in some cases.
