the   contents   of   the   specified   data   memory
location and W, and writes the 8-bit result into the
same data memory location. W is left unchanged.
If the result is zero, the Z bit is set. Cycles: 1 Example: and 0x099,W This example performs a bitwise logical AND of
the working register W with a value stored in data
memory location 0x099. The result is written back
to the data memory location. For  example,  suppose  that  the  data  memory
location 0x099 holds the value 0x0F and W holds
the value 0x13. The instruction takes the logical
AND of 0x0F and 0x13 and writes the result 0x03
