6 BASIC INSTRUCTIONS
6.2 Arithmetic Operation Instructions
DDIV(P)(_U)
These instructions divide the 32-bit binary data in the device specified by (s1) by the 32-bit binary data in the device specified
by (s2), and store the result in the device specified by (d).
■Descriptions, ranges, and data types
■Applicable devices
• These instructions divide the 32-bit binary data in the device specified by (s1) by the 32-bit binary data in the device
specified by (s2), and store the division result in the device specified by (d).
■Related flag
■Operation result
• The most significant bit of the quotient and remainder indicates the sign (positive: 0, negative: 1), respectively.
• The quotient is negative when either (s1) or (s2) is negative. The remainder is negative when the (s1) is negative.
■Device specified by (d)
• The remainder is not obtained when a bit device is specified with nibble specification.
