Processing details
• These instructions subtract the BCD 4-digit data in the device specified by (s1) and the BCD 4-digit data in the device
specified by (s2), and store the subtraction result in the device specified by (d).
• If an underflow occurs, the result will be as follows. In this case, the carry flag (SM700) does not turn ON.
