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-

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 al-
ways the accumulator.
