The value at source A is divided by the value at source B with the rounded
quotient being stored in the destination. If the remainder is 0.5 or greater,
round up occurs in the destination. The unrounded quotient is stored in the
most significant word of the math register. The remainder is placed in the
least significant word of the math register.
Using Arithmetic Status Bits
C always reset
V set if division by zero or overflow; otherwise reset. On overflow, the
minor error flag is also set. The value 32,767 is placed in the destination.
Exception: If you are using a Series C or later SLC 5/02 processor and
have the Math Overflow Selection Bit S:2/14 set, then the unsigned,
truncated overflow remains in the destination.
Z set if the result is zero; otherwise reset; undefined if overflow is set
S set if the result is negative; otherwise reset; undefined if overflow is set
Math Register
The unrounded quotient is placed in the most significant word, the remainder
is placed in the least significant word.
