Precautions for the STOP mode
Set 1 to the bit 0 (OSCD1) of STCR register. When shifting to the STOP mode, a regulator switches to the stand-
by regulator (for low-consumption current).
Due to the limited drive current, stop the (programming/erasing) access to the A/D converter and Flash before
shifting to the STOP mode.
Serial communication
There is a possibility to receive wrong data due to the noise or other causes on the serial communication.
Therefore, design a board so as to avoid noise.
Consider receiving of wrong data when designing the system. For example, apply a checksum to detect an error.
If an error is detected, retransmit the data.
Notes on using external clock
When using the external clock, as a general rule you should simultaneously supply X0 and X1 pins. And also,
the clock signal to X0 should be supplied a clock signal with the reverse phase to X1 pins. However, in this case
the stop mode (oscillation stop mode) must not be used.
Notes on operating in PLL clock mode
If the oscillator is disconnected or the clock input stops when the PLL clock is selected, the microcontroller may
continue to operate at the free-running frequency of the self-oscillating circuit of the PLL. However, this self-
running operation cannot be guaranteed.

Note : Stop mode (oscillation stop mode) cannot be used.
