6.2 Arithmetic Operation Instructions
Dividing 16-bit binary data
/(P)(_U) instruction and DIV(P)(_U) instruction can be used for division of 16-bit binary data.
/(P)(_U)
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 result in the device specified by (d).

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).
• For the division result, 32-bit is used for word device to store the quotient and remainder and 16-bit is used for bit device to
store quotient only.
