MPC823e Instruction Set
Precedence rules for pseudocode operators are summarized in the following table.
Operators in the top part of the table above are applied before those in the lower part.
Operators at the same level in the table associate from left to right, from right to left, or not
at all. For example, "–" (unary minus) associates from left to right, so a – b – c = (a – b) – c.
Parentheses are used to override the evaluation order implied by the table above, or to
increase clarity and parenthesized expressions are evaluated before serving as operands.
B.5 THE MPC823e INSTRUCTION SET
The remainder of this section lists and describes the MPC823e instruction set. The
instructions are listed in alphabetical order by their mnemonic.
Note: The execution unit that executes the instruction may not be the same for all
PowerPC processors.
