RL78/G1D
12.3.10 A/D test register (ADTES)
This register is used to select the + side reference voltage or - side reference voltage for the converter, an analog input
channel (ANIxx), the temperature sensor output voltage, or the internal reference voltage (1.45 V) as the target for A/D
conversion.
When using this register to test the converter, set as follows.
● For zero-scale measurement, select the - side reference voltage as the target for conversion.
● For full-scale measurement, select the + side reference voltage as the target for conversion.
The ADTES register can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Address: F0013H After reset: 00H R/W

Note The temperature sensor output voltage and internal reference voltage (1.45 V) can be selected only in
the HS (high-speed main) mode.
