Description
This instruction divides the contents of a 16-bit register Rd (destination operand) by the contents
of an 8-bit register Rs (source operand) and stores the result in the 16-bit register Rd. The division
is signed. The operation performed is 16 bits
quotient is placed in the lower 8 bits of Rd. The remainder is placed in the upper 8 bits of Rd. The
sign of the remainder matches the sign of the dividend.
Valid results are not assured if division by zero is attempted or an overflow occurs.
Available Registers
