A <- A + n + CY
The n integer along with the Carry Flag (C in the F Register) is added to the contents of the Accumulator, and the results are stored in the Accumulator.
|S||is set if result is negative, otherwise it is reset.|
|Z||is set if result is 0, otherwise it is reset.|
|H||is set if carry from bit 3, otherwise it is reset.|
|P/V||is set if overflow, otherwise it is reset|
|C||is set if carry from bit 7, otherwise it is reset.|
If the Accumulator contains $23 and the Carry Flag is set then upon the execution of
the Accumulator contains $57.
