== Effects ==<br />
<br />
<!-- What the instruction does to flags --><br />
Sets H and N, other flags are unmodified.<br />

== Uses ==<br />
<br />
<!-- What the instruction can be used for --><br />
This instruction returns the same value as XORing A with $FF or subtracting A from $FF.<br />
Also, CPL \ INC A returns the same value that NEG does.<br />
