S2
Decimal: S1 = 18 and S2 = 3
Hexadecimal: S1 = $12 and S2 = $03
DIV Example:
Decimal: 18
÷
3 = 6
DIVB Example:
BCD: $12
÷
$03 = $04
Description
1. Divide the data in S1 by S2, then store the result in the D register.
2. When using DIV and DIVB, the calculation ranges are as follows:
S1: 0 to 65,535 ($0000 to $FFFF)
S2: 0 to 65,535 ($0000 to $FFFF)
D: 0 to 65,535 ($0000 to $FFFF)
3. When using DDIV and DDIVB, the calculation ranges are as follows:
S1: 0 to 4,294,976,295 (0 to $FFFFFFFF)
S2: 0 to 4,294,976,295 (0 to $FFFFFFFF)
D: 0 to 4,294,976,295 (0 to $FFFFFFFF)
4. The quotient is stored in the D register, and the remainder in special register SR22.
5. This operation will occur on every scan for which the input condition is true (On). To perform
the operation only on a change of input condition, use the rising/falling edge contact.
