IP2022 User’s Manual—Instruction Set Architecture www.ubicom.com 227 XOR fr,W XOR fr,W into fr Operation: fr = fr ^ W Bits affected: Z Opcode: 0001 101f ffff ffff Description: This instruction performs a bitwise exclusive OR
of  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: xor    0x099,w ;move fr XOR W to fr This example performs a bitwise logical XOR of
W  with  a  value  stored  in  data  memory  location
0x099.  The  result  is  written  back  to  the  data
memory location 0x099.
For  example,  suppose  that  the  data  memory
location  0x099  is  holds  the  value  0x0F  and  W
holds  the  value  0x13.  The  instruction  takes  the
logical  XOR  of  0x0F  and  0x13  and  writes  the
