Instruction Set Architecture—IP2022 User’s Manual 188 www.ubicom.com OR W,#lit8 OR W,Literal into W Operation: W = W | lit8 Bits affected: Z Opcode: 1101 kkkk kkkk kkkk Description: This instruction performs a bitwise logical OR of
the contents of W and an 8-bit literal value, and
writes the 8-bit result into W. If the result is zero,
the Z bit is set. Cycles: 1 Example: or w,#0x0F;set low four W bits This example performs a bitwise logical OR of W
with  the  literal  value  0x0F.  The  result  is  written
back to W. For  example,  suppose  that  W  holds  the  value
0x50. The instruction takes the logical OR of this
value with 0x0F and writes the result 0x5F into W.
The result is nonzero, so the Z bit is cleared.
