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 |
| N | 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
ADC A,$33
the Accumulator contains $57.
