Notes:
1. When the CM06 bit is set to 0, bits CM16 and CM17 are enabled.
2. When the CM10 bit is set to 1 (stop mode), the on-chip feedback resistor is disabled.
3. When the OCD2 bit is set to 0 (XIN clock selected), the CM14 bit can be set to 1 (low-speed on-chip oscillator
4. To use P12_0 and P12_1 as input ports, set the CM13 bit to 0 (I/O ports), the CM05 bit in the CM0 register to 1
5. Once the CM13 bit is set to 1 by a program, it cannot be set to 0.

off). When the OCD2 bit is set to 1 (on-chip oscillator clock selected), the CM14 bit is set to 0 (low-speed on-chip
oscillator on). It remains unchanged even if 1 is written to it.
(XIN clock stops), and the CM07 bit to 1 (XCIN clock).
To use as external clock input, set the CM13 bit to 0 (I/O ports), the CM05 bit to 1 (XIN clock oscillates), the
CM07 bit to 0 (XIN clock). When the PD12_0 bit in the PD12 register is further set to 0 (input mode), an external
clock can be input. XOUT can be used as the input port P12_1 at this time.
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.
Set the PRC0 bit in the PRCR register to 1 (write enabled) before rewriting the CM1 register.
