21.7.2
If no subclock is required, connect the OSC1 pin to Vss and leave the OSC2 pin open, as shown in
figure 21.10. The SUBSTP bit in LPWRCR must be set to 1.
If the SUBSTP bit is not set to 1, transitions to the power-down mode may not complete normally.
21.8
To eliminate noise from the subclock input from the OSC1 pin, the subclock is sampled using the
dividing clock φ. The sampling frequency is set using the NESEL bit in LPWRCR. For details, see
section 21.1.2, Low-Power Control Register (LPWRCR).
No sampling is performed in watch mode.
