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 operation result in the device specified by (d).
(s1)
b15 b0 b15
···
÷
5678 (BIN) 1234 (BIN)
(d): Quotient
(d)+1: Remainder
• As the operation result, the quotient and remainder are stored in 32 bits. When a bit device is specified, the number of digit-
specified bits is used to store the quotient and remainder.
• Quotient⋅⋅⋅Stored in lower 16 bits.
• Remainder⋅⋅⋅Stored in upper 16 bits.
Operation error
Error code Description
3400H The value (divisor) in the device specified by (s2) is 0.
