6 BASIC INSTRUCTIONS
6.2 Arithmetic Operation Instructions
D-(P)(_U) [using three operands]
These instructions subtract the 32-bit binary data in the device specified by (s1) and the 32-bit binary data in the device
specified by (s2), and store the result in the device specified by (d).

Processing details
• These instructions subtract the 32-bit binary data in the device specified by (s1) and the 32-bit binary data in the device
specified by (s2), and store the subtraction result in the device specified by (d).
• When underflow or overflow occurs in the operation result, the following processing is executed. In this case, the carry flag
(SM700, SM8022) does not turn ON.
Operation error
There is no operation error.

In case of D-(P)
Because the highest bit is 1, the value is negative.
In case of D-(P)(_U)
Because the highest bit is 0, the value is positive.
