specified  data  memory  location  and  writes  the
result back into the same register. If the result is
zero, the Z bit is set. Cycles: 1 Example: not    0x099 ;complement 0x099 Suppose that data memory location 0x099 holds
the   value   0x1C.   This   instruction   takes   the
complement of 0x1C and writes the result 0xE3
back to location 0x099. The result is nonzero, so
the Z bit is cleared.
