21.6.2
If no subclock is required, connect the OSC1 pin to Vss and leave OSC2 open, as shown in figure
21.10. Set the SUBSTP bit of LPWRCR to 1.
21.7
To eliminate noise from the subclock input to OSCI, the subclock is sampled using the dividing
clock φ. The sampling frequency is set using the NESEL bit of LPWRCR. For details, see section
21.1.2, Low Power Control Register (LPWRCR).
No sampling is performed in sub-active mode, sub-sleep mode, or watch mode.

21.8.1
As various characteristics related to the crystal resonator are closely linked to the user's board
design, thorough evaluation is necessary on the user's part, using the resonator connection
examples shown in this section as a guide. As the resonator circuit ratings will depend on the
floating capacitance of the resonator and the mounting circuit, the ratings should be determined in
consultation with the resonator manufacturer. The design must ensure that a voltage exceeding the
maximum rating is not applied to the oscillator pin.
