Operand

Description

1

RXY

LOAD the register R with the bit pattern found in the memory cell whose address is XY

2

RXY

LOAD the reqister R with the bit XY

3

RXY

STORE the bit pattern found in register R in the memory cell whose address is XY

4

ORS

MOVE te bit pattern found in register R to reqister S

5

RST

ADD the bit patterns in registers S and T as though they were two's complement representations and leave the result in register R

6

RST

ADD the bit patterns in registers S and T as though they represented values in floating-point notation and leave the result in reqister R

7

RST

OR the bit pattern in registers S and T and place the result in reQister R

8

RST

AND the bit patterns in register S and T and place the result in register R

9

RST

Exclusive OR the bit patterns in registers S and T and place the result in register R

A

ROX

ROTATE the bit pattern in register R one bit to the right X times. Each time place the bit that started at the low-order end at the hiQh-order end.

B

RXY

JUMP to the instruction located in the memory cell at address XY if the bit pattern in register R is equal to the bit pattern in register number 0. Otherwise, continue with the normal sequence of execution.

c

000

HALT execution
