literal value, and writes the 8-bit result into W. If the result is 00h, the Z bit is set. Cycles: 1 Example: xor W,$#0F ;complement four low-order bits of W This example performs a bitwise logical XOR of W with the literal value #0Fh. The
result is written back to W. For  example,  suppose  that  W  contains  the  value  51h.  The  instruction  takes  the
logical XOR of this value with 0Fh and writes the result, 5Eh, into W. The result is
nonzero, so the Z bit is cleared.
