DIVXS (DIVide eXtend as Signed)
DIVXS.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 operand) and stores the result in the 32-bit register ERd. The
division is signed. 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 (Ed). The sign of the remainder matches the sign of the
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
Section 2 Instruction Descriptions
H: Previous value remains unchanged.
N: Set to 1 if the quotient is negative;
otherwise cleared to 0.
Z: Set to 1 if the divisor is zero; otherwise
cleared to 0.
V: Previous value remains unchanged.
C: Previous value remains unchanged.
