A/D Test Register (Adtes) - Renesas RL78/G1P Hardware User Manual

RL78/G1P

9.3.10 A/D test register (ADTES)

This register is used to select the + side reference voltage or  side reference voltage of the A/D converter, or the
analog input channel (ANIxx), the temperature sensor output voltage, or the internal reference voltage (1.45 V) as the A/D
conversion target for the A/D test function.
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.
For detail, refer to Figure 22-3 Format of User Option Byte (000C2H).
Caution For the A/D test function, see 20.10 A/D test function.
