Caution
• When underflow or overflow occurs in the operation result, the following processing is executed. At this time, the
carry flag does not turn ON.
- In the case of 16-bit operation
K32767(H7FFF)
K-32768(H8000)
- In the case of 32-bit operation
K2,147,483,647(H7FFFFFFF)
K-2,147,483,648(H80000000)
• Note that the 32-bit value [n+1, n] is valid when D or R is specified as "n" in a 32-bit instruction.
In the case of "DBK+ D0 D100 D200 R0", "n" is [R1, R0].
