It performs addition function with carry. This adds the source byte to the accumulator(A) with carry bit i.e., A = A + byte + CY. If CY prior to this instruction, CY is also added to A. This instruction is the same as to ADD A, byte.

Example:

ADDC A, R4
Add register to A with carry, but puts the sum in the accumulator.
