DIVXU (DIVide eXtend as Unsigned)
DIVXU.W Rs, ERd
This instruction divides the contents of a 32-bit register ERd (destination operand) by the contents
of a 16-bit register Rs (source register) and stores the result in the 32-bit register ERd. The
division is unsigned. The operation performed is 32 bits
remainder. The quotient is placed in the lower 16 bits (Rd) of the 32-bit register ERd. The
remainder is placed in the upper 16 bits of (Ed).
Valid results are not assured if division by zero is attempted or an overflow occurs.
ERd: ER0 to ER7
R0 to R7, E0 to E7
H: Previous value remains unchanged.
N: Set to 1 if the divisor is negative;
Z: Set to 1 if the divisor is zero; otherwise
V: Previous value remains unchanged.
C: Previous value remains unchanged.
otherwise cleared to 0.
cleared to 0.
