Processing details
• These instructions subtract the BCD 4-digit data in the device specified by (s) from the 32-bit binary data in the device
specified by (d), and store the operation result in the device specified by (d).
• If an underflow occurs, the result will be as follows. In this case, SM700 does not turn on.
