Operation:

(D)

÷ (X) ⇒ X; Remainder ⇒ D

Description:

Divides an unsigned 16-bit dividend in double accumulator D by an

unsigned 16-bit divisor in index register X, producing an unsigned 16-bit

quotient in X, and an unsigned 16-bit remainder in D. If both the divisor and

the dividend are assumed to have radix points in the same positions, the

radix point of the quotient is to the right of bit 0. In the case of division by

zero, C is set, the quotient is set to $FFFF, and the remainder is

indeterminate.
