Using Bit-Wise Operations
More often than not, when working with the SPRM values, you will only be interested in
certain bits of each 16-bit value. The “bit-wise” operations (and, or, and exclusive or),
make it possible to mask the bits that are not needed, allowing you to determine the
states of the specific bits you need.
Note: You need to have a basic understanding of working with binary numbers to be
able to use these operations.
