Adds the source operand to the destination operand, which can be a register or the accumulator, leaving the result in the register or accumulator. If there is a carry out of bit 7 (CY), the CY flag is set. If byte variables are added, and if there is a carry out of bit 3 (AC), the AC flag is set. For addition of unsigned integers, the CY flag of TSC80251 indicates that an overflow occurred.

If there is a carry out of bit 6 but not out of bit 7, or a carry out of bit 7 but not bit 6, the OV flag is set. When adding signed integers, the OV flag of TSC80251 indicates a negative number produced as the sum of two positive operands, or a positive sum from two negative operands.
