INSTRUCTION SET (Cont’d)
Arithmetic and Logic. 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.
