Operands:

: Summand S

: Addend D: Sum

Explanations:

1. This instruction adds S

and S

in BIN format and store the result in D.

2. The most significant bit (MSB) is the sign bit of the data. 0 indicates positive and 1 indicates

negative. All calculations is algebraically processed, e.g. 3 + (-9) = -6.

3. If S

, S

and D use device F, only 16-bit instruction is applicable.

4. Flags: M1020 (Zero flag), M1021 (Borrow flag), M1022 (Carry flag)

Program Example 1:

In 16-bit BIN addition:

When X0 = ON, the content in D0 will plus the content in D10 and the sum will be stored in D20.

ADD D0 D10 D20

Program Example 2:

In 32-bit BIN addition:

When X0 = ON, the content in (D31, D30) will plus the content in (D41, D40) and the sum will be

stored in (D51, D50). D30, D40 and D50 are low word; D31, D41 and D51 are high word

DADD

D30 D40 D50

(D31, D30) + (D41, D40) = (D51, D50)

Operation of flags:

16-bit instruction:

1. If the operation result is “0”, the zero flag M1020 will be ON.

2. If the operation result exceeds -32,768, the borrow flag M1021 will be ON.

3. If the operation result exceeds 32,767, the carry flag M1022 will be ON.

32-bit instruction:

1. If the operation result is “0”, the zero flag, M1020 will be ON.
