These instructions are used to perform arithmetic calculations and logic operations. In AND, ADD, CP, SUB instructions one operand is always the accumulator while, de- pending on the addressing mode, the other can be either a data space memory location or an imme- diate value. In CLR, DEC, INC instructions the op- erand can be any of the 256 data space address- es. In COM, RLC, SLA the operand is always the accumulator. Table 16.
