1.
Read value of 0x30 register address is 0xB9 and read value of 0x31 register
address is 0x3, then the ADC output value is 0x3B9, or in decimal, 953. Hence,
ADC_Output_Value=953
2. MAX 10 internal reference voltage is used so
VREF = 3.3 V
3.
Divider resistor values are R217 = 316 ohm and R216 = 316 ohm, so
R_Divider = R217/R216 + 1 = 2
4.
Calculated the analog signal voltage on ARDUINO_ANA0 (J6.1) is
Voltage @ ARDUINO_ANA0 = (953/4096) * 3.3 * 2 = 1.54 V

4.9.3.3 Arduino Power
There are several power rails on the Arduino connectors.
• IOREF: 3.3 V for digital IOs. It must be 3.3 V. 5 V is forbidden as it may damage
devices on the board.
• VCC_3.3V: 3.3 V power generated by Intel Cyclone 10 LP FPGA Evaluation Board.
• VCC_5V_AR1/2: 5 V power from Intel Cyclone 10 LP FPGA Evaluation Board.
• ARDUINO_AREF: Reserved analog reference voltage. Care must be taken that
the range can be 0 ~3.3 V. 5 V is forbidden.
