2.3 EXTENDED ADDITION Instruction (ADDX)

[Outline]

The ADDX instruction adds integer values. Source B is added to Source A and stored in the Dest. No

operation error occurs, even if the operation results in an overflow. Otherwise, the ADDX is much the

same as the ADD.

[Format]

Symbol : ADDX

Full Name : Expanded Add

[Parameter]

Parameter Name Setting

Source A · Any integer type and double-length integer type register

· Any integer type and double-length integer type register with subscript

· Subscript register

· Constant

Source B · Any integer type and double-length integer type register

· Any integer type and double-length integer type register with subscript

· Subscript register

· Constant

Dest · Any integer type and double-length integer type register (except for # and

C registers)

· Any integer type and double-length integer type register with subscript

(except for # and C registers)

· Subscript register

[Program Example]

This instruction is used in cases where it is desirable that operation errors do not occur in the addition

of integer type values.

Notes: In the case of double-length integer type values, an operation using addition and

subtraction instructions (+, –, ++, --) will be a 32-bit operation. However, when an

addition or subtraction instruction is used in a remainder correction operation (where a

multiplication instruction (×) is the immediately preceding instruction and a division

instruction (÷) is the immediately subsequent instruction), the operation will be a 64-bit

operation.
