Parity 0: None
With no parity, data can only be converted when the leftmost bit is zero. If it is not
set to zero, the Error Flag will turn ON and the data will not be converted.
1: Even
The data (8 bits) can only be converted when the number of “1” bits is even. If the
number is odd, the Error Flag will turn ON and the data will not be converted.
