Flags Affected
Dest Source S Z H P/V N C
Note: *This flag value is a function of the result of the affected operation.
— = No Change.
0 = Set to 0.
1 = Set to 1.
V = Set to 1 if overflow occurs.
X = Undetermined.
P = Set to the parity of the result (0 if odd parity, 1 if even parity).
IEF2 = The value of Interrupt Enable Flag 2.
