N Set if the most significant bit of the result is set. Cleared otherwise.
Z Set if the result equals zero. Cleared otherwise.
C Set if a carry or borrow is generated. Cleared otherwise.
SV Set if an arithmetic overflow occurred. Not affected otherwise.
E Set if the MAE is used. Cleared otherwise.
SL Set if the contents of the ACC is automatically saturated. Not affected otherwise.
