3.2.3 Logical Instructions
3-6
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 oper'ations 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 operation,s.
