Details
A field of bits is a contiguous group of bits. This function retrieves a field of bits from value starting at index.
The index position is the least significant bit of the retrieved field. The number of bits to return is specified by
width.
The least significant bit value is at index position 1; the most significant bit is at index position 32.
Example
myResult = bit.getfield(13, 2, 3)
print(myResult)
