IP2022 User’s Manual—Instruction Set Architecture www.ubicom.com 187 OR W,fr OR W,fr into W Operation: W = W | fr Bits affected: Z Opcode: 0001 000f ffff ffff Description: This instruction performs a bitwise logical OR 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: or w,0x099;move W OR fr to W This example performs a bitwise logical OR 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
OR of 0x0F and 0x13 and writes the result 0x1F
into  W.  The  result  is  nonzero,  so  the  Z  bit  is
cleared.
