INSTRUCTION SET (Cont’d)

Arithmetic and Logic. These instructions are

used to perform the arithmetic calculations and

logic operations. In AND, ADD, CP, SUB instruc-

tions one operand is always the accumulator while

the other can be either a data space memory con-

tent or an immediate value in relation with the ad-

dressing mode. In CLR, DEC, INC instructions the

operand can be any of the 256 data space ad-

dresses. In COM, RLC, SLA the operand is always

the accumulator.
