2.5 EXTENDED SUBTRACTION Instruction (SUBX)

[Outline]

The SUBX instruction subtracts integer values. No operation error occurs, even if the operation

results in an underflow.

[Format]

Symbol : SUBX

Full Name : Expanded Subtract

Category : MATH

Icon :

[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

subtraction 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.
