Calculate Odd Parity (P column)
If there is an Even Number of 1’s in the row of data for each character, put a 1 in the P column. Other wise, put a 0 in
the column.
LRC: If there is an Even Number of 1’s in the column of data for each character, put a 0 in the LRC row. Other wise,
put a 0 in the row. The last LRC will be considered as the parity rule of this row.
