24.3.6.1 A/D test registers (ADTES).
This register selects the A/D converter's positive (+) reference, negative () reference, analog input
channel (ANIxx), temperature sensor output voltage, and internal reference voltage (1.45V). as an A/D
conversion object.
When used as an A/D test function, the following settings are made:
When measuring the zero scale, select the negative () reference voltage as the A/D conversion
object.
When measuring the full scale, select the positive (+) reference voltage as the A/D conversion
object.
Refer to 11.2 10.
24.3.6.2 The analog input channel specifies registers (ADS).
This register specifies the input channel for the analog voltage of the A/D conversion.
To measure an ANIxx, temperature sensor output, or internal reference voltage (1.45V) through the A/D
test function, the A/D test register (ADTES) must be set to 00H.
Refer to 11.2.7 for a description of the registers.
