32.3.6.1
A/D Test Register (ADTES).
This register selects the positive (+) reference voltage, negative (
–) reference voltage, analog input
channel (ANIxx), output voltage of the temperature sensor, and internal reference voltage (1.45V) of the A/D
converter ) 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 full scale, select a positive (+) reference voltage as the A/D conversion object.
For a register description, refer to 15.2

32.3.6.2
Analog input channel specified register (ADS).
This register specifies the input channel for the analog voltage converted from A/D.
To measure ANIxx, temperature sensor output, or internal reference voltage (1.45V) via the A/D test
function, the A/D test register (ADTES) must be placed at "00H"
。
For a register description, refer to 15.2.7.
