7 BASIC INSTRUCTIONS
7.2 Arithmetic Operation Instructions
Subtracting 16-bit binary data
-(P)(_U) instruction and SUB(P)(_U) instruction can be used for subtraction of 16-bit binary data.
-(P)(_U) [using two operands]
These instructions subtract the 16-bit binary data in the device specified by (d) and the 16-bit binary data in the device
specified by (s), and store the result in the device specified by (d).

Processing details
• These instructions subtract the 16-bit binary data in the device specified by (d) and the 16-bit binary data in the device
specified by (s), 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.
