IP2022 User’s Manual—Instruction Set Architecture www.ubicom.com 117 AND W,fr AND W,fr into W Operation: W = W & fr Bits affected: Z Opcode: 0001 010f ffff ffff Description: This instruction performs a bitwise logical AND of
the contents of W and the specified data memory
location,  and writes the  8-bit result  into  W. The
data  memory  location  is  left  unchanged.  If  the
result is zero, the Z bit is set. Cycles: 1 Example: and     w,0x099 This example performs a bitwise logical AND of
the value stored in data memory location 0x099
with W. The result is written back to W. 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
into  W.  The  result  is  nonzero,  so  the  Z  bit  is
cleared.
