Bit
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
the CMOS level signal directly.
