Note: In this time, bit 6 of the serial I/O control register (address 001A16) is set to “1” (clock synchronous serial I/O is selected).
When bit 6 of the serial I/O control register is “0” (clock asynchronous serial I/O is selected), the rating values are divided by 4.

Note: As for AD translation accuracy, on the following operating conditions, accuracy may become low.
(1) Since the analog circuit inside a microcomputer becomes sensitive to noise when VREF voltage is set up lower than Vcc voltage,
accuracy may become low rather than the case where VREF voltage and Vcc voltage are set up to the same value..
(2) When VREF voltage is less than [ 3.0V ], the accuracy at the time of low temperature may become extremely low compared with
the time of room temperature. The use beyond VREF=3.0V is recommended in the system the use by the side of low temperature
is assumed to be.
