The data is treated as signed binary 16-bit data using the leftmost bit as the
sign bit. The value is expressed in 4-digit hexadecimal.
Positive numbers: If the leftmost bit is OFF, it indicates a non-negative value.
For 4-digit hexadecimal, the value will be 0000 to 7FFF hex.
Negative numbers: If the leftmost bit is ON, it indicates a negative value. For
4-digit hexadecimal, the value be 8000 to FFFF hex and it will be expressed
as the 2's complement of the absolute value of the negative value (decimal).
