1. These pins can be used as P12_0 and P12_1 when using the on-chip oscillator clock as the CPU clock while
2. To input an external clock, set the CM05 bit in the CM0 register to 1 (XIN clock stops), the CM11 bit in the CM1

the XIN clock oscillation circuit and the XCIN clock oscillation circuit are not used.
The P12_0 pin is shared with the XIN pin, and the P12_1 pin is shared with the XOUT pin. These pins cannot
be used as I/O ports when using the XIN clock.
