1. Pulled up by setting the PU10 bit in the PUR1 register to 1.
2. Output drive capacity high by setting the DRR10 bit in the DRR1 register to 1.
3. When the XCIN clock is used, set the PU10 bit in the PUR1 register to 0 (not pulled up).
1. Pulled up by setting the PU11 bit in the PUR1 register to 1.
2. Output drive capacity high by setting the DRR11 bit in the DRR1 register to 1.
3. Since the XCIN-XCOUT oscillation buffer operates with internal step-down power, the XCOUT output level cannot be used as
4. When the XCIN clock is used, set the PU11 bit in the PUR1 register to 0 (not pulled up).
