8.2.1
Notes:
1. The CM05 bit can be used to stop the XIN clock when the system clock is other than the XIN clock. This bit
2. During external clock input, only the clock oscillation buffer stops and clock input is acknowledged.
3. Only when the CM05 bit to 1 (XIN clock stops) and the CM07 bit is set to 1 (XCIN clock), P12_0 and P12_1 can
4. When the MCU enters stop mode, the CM06 bit is set to 1 (divide-by-8 mode).
5. Set the CM07 bit to 1 (XCIN clock) from 0 after allowing the XCIN clock oscillation to stabilize.
6. To use the XCIN clock, set the CM03 bit to 1 once and then set it to 0 (XCIN clock oscillates) after turning on the

cannot be used to detect whether the XIN clock has stopped. To stop the XIN clock, set the bits in the following
order:
(a) Set bits OCD1 to OCD0 in the OCD register to 00b.
(b) Set the OCD2 bit to 1 (on-chip oscillator clock selected).
be used as I/O ports.
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.
power. To use the VL1 internally-generated voltage in the LCD drive control circuit, set the LVURS bit in the
LCR1 register to 1 (VL1 internally-generated voltage) after the above setting.
Set the PRC0 bit in the PRCR register to 1 (write enabled) before rewriting the CM0 register.
