Processing details
• These instructions divide the 16-bit binary data in the device specified by (s1) by the 16-bit binary data in the device
specified by (s2), and store the division result in the device specified by (d).

(d): Quotient
(d)+1: Remainder
• Two devices in total starting from the one specified by (d) are used to store the division result. Make sure that these two
devices are not used for another control.
• Quotient...... Stored in the lower 16 bits.
• Remainder...... Stored in the upper 16 bits.
