Hi Steve,

yes, it is.
C is wonderful self documenting:

The function name "parity" describe exactly, what it should do.
The input and output parameters are complete described by its type definitions: "char" and "bit".
So no need for any additional comments.
Only complex functions should be commented moreover.

Following the generated code. But its not wise, to build a function for such small code (waste of LCALL and RET). Better, use a macro:

#define parity( x ) ( ACC = x, P )
