Operation
Rd ÷ Rs
Assembly-Language Format
DIVXU Rs, Rd
Operand Size
Byte
Description
This instruction divides a 16-bit general register by an 8-bit general register and places the result
in the 16-bit general register. The quotient is placed in the lower byte. The remainder is placed in
the upper byte. The operation is shown schematically below.
Valid results (Rd, N, Z) are not assured if division by zero is attempted or an overflow occurs.
Division by zero is indicated in the Zero flag. Overflow can be avoided by the coding shown on
the next page.
