Use Appendix A of the MPCFPE32B.pdf file or Appendix B of the MPC823UM.pdf file.

These files can be loaded using the following links:

The "lis" instruction is equivalent to addis rD,0,value instruction.

Definition: Add Immediate Shifted

Operation: if rA = 0 then rD " EXTS(SIMM || (16)0)

else rD " (rA) + EXTS(SIMM || (16)0)

Description: The sum (rA|0) + (SIMM || 0x0000) is placed into rD.

The addis instruction is preferred for addition because it sets few status bits. Note that addis uses the value 0, not the contents of GPR0, if rA = 0.

Have a great day,
