2. P124 is connected to sub-clock XT2 by default. When P124 is to be used as a port pin, cut the pattern for
cutting [XT2] and short-circuit the short-circuit pad [P124].
3. P123 is connected to sub-clock XT1 by default. When P123 is to be used as a port pin, cut the pattern for
cutting [XT1] and short-circuit the short-circuit pad [P123].
