Arithmetic Operation Instructions
Adding 16-bit binary data
+(P)(_U) instruction and ADD(P)(_U) instruction can be used for addition of 16-bit binary data.
+(P)(_U) [using two operands]
These instructions add 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 add the 16-bit binary data in the device specified by (s) to the 16-bit binary data in the device specified
by (d), and store the addition 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 +(P)
Because the highest bit is 1, the value is negative.
In case of +(P)(_U)
Because the highest bit is 0, the value is positive.
