Operands:
S
1
: Dividend S
2
: Divisor D : Quotient and remainder
Explanations:
1. In 16-bit instruction, D occupies 2 consecutive devices.
2. This instruction divides S
1
and S
2
in BIN format and stores the result in D . Be careful with
the positive/negative signs of S
1
, S
2
and D when doing 16-bit and 32-bit operations.
16-bit instruction:
+1
= /
Quotient
Remainder
Program Example:
When X0 = On, D0 will be divided by D10 and the quotient will be stored in D20 and remainder in
D21. On/Off of the highest bit indicates the positive/negative status of the result value.
