9.3.10 A/D test register (ADTES)
This register is used to select the + side reference voltage or
side reference voltage of the A/D converter, or the
analog input channel (ANIxx), the temperature sensor output voltage, or the internal reference voltage (1.45 V) as the A/D
conversion target for the A/D test function.
The ADTES register can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
