<Control register>
(1) A/D test register (ADTES)
This register is used to select the A/D converter’s positive reference voltage AV
REFP, the A/D converter’s negative
reference voltage AV
REFM, or the analog input channel (ANIxx) as the target of A/D conversion.
When using the A/D test function, specify the following settings:
• Select AV
REFM as the target of A/D conversion when converting the internal 0 V.
• Select AV
REFP as the target of A/D conversion when converting AVREF.
• Select ANIxx as the target of A/D conversion when converting the internal reference voltage (1.45 V), and specify
the internal reference voltage output as the input source in the ADS register.
The ADTES register can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
