16-by-16 Signed Division
DIV op1
(MDL) ← (MDL) / (op1)
(MDH) ← (MDL) mod (op1)
WORD
Performs a signed 16-bit by 16-bit division of the low order word stored in
the MD register by the source word operand op1. The signed quotient is
then stored in the low order word of the MD register (MDL) and the
remainder is stored in the high order word of the MD register ( MDH).
E Z
0 *
E Always cleared.
Z Set if result equals zero. Cleared otherwise.
V Set if an arithmetic overflow occurred, ie. the result cannot be repre-
sented in a word data type, or if the divisor (op1) was zero. Cleared
otherwise.
C Always cleared.
N Set if the most significant bit of the result is set. Cleared otherwise.
