33 columns. The parity used is even parity which means that the parity bit = 1
34 if the data over which the parity is calculated is 1 and the parity bit = 0
35 if the data over which the parity is calculated is 0. So the total
36 number of bits over the data over which the parity is calculated + the
37 parity bit is even. (see wikipedia if you can't follow this).
59 cp is my abbreviation for column parity, rp for row parity.
61 Let's start to explain column parity.
63 - cp0 is the parity that belongs to all bit0, bit2, bit4, bit6.
69 - cp2 is the parity over bit0, bit1, bit4 and bit5
