(2) Analog input channel specification register (ADS)
This register specifies the input channel of the analog voltage to be A/D converted.
Select ANIxx as the target of A/D conversion by ADTS register when converting the internal reference voltage (1.45
V), and specify the internal reference voltage output as the input source in the analog input channel specification
register (ADS).
The ADS register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
