3.2.3 Logical Instructions
The logical operation instructions (AND, OR, EOR, and NOT) perform logical operations
with all sizes of integer data operands. A similar set of immediate instructions (ANDI, ORI,
and EORI) provide these logical operations with all sizes of immediate data. The TST
instruction compares the operand with zero arithmetically, placing the result in the condition
code register. Table 3–3 summarizes the logical operations.
