• The return value is 2 bytes wide signed (two's complement) value, the unit is 1 V, the resolution is 1/16 V = 0.0625 V, and the range is ±2,047.9375 V. Value 0x8000 (i.e. -2,048 V) specifies a sensor error.

bit: 0…3 Fractional part (unit 1/16 V).
bit: 4…14 Integer part (unit 1 V).
bit: 15 Sign.
• FRC 2-byte: FRC value is 2-byte return value +0x8000 that actually causes inverting of the most significant sign bit (i.e. 0x8000 is 0.0 V, 0x8E60 is 230.0 V, 0x7F40 is -12.0 V). Because of FRC predefined values the raw values from 0x8000 to 0x8003 (i.e. -2,047.8125 V to -2,047.9375 V) cannot be passed.
