[Parity]
When the total number of "1"s or "0"s in the display data and dimming data is even,
add "P0, P1=1, 1" to input data, and when it is odd, add "P0, P1=0, 0".

[Parity]
When the total number of "1"s or "0"s in the key switch data is even, "P0, P1=1, 1" is
added to the output, and when it is odd, "P0, P1=0, 0" is added.
Note:
"1" is output to every bit from bit 27 to bit 58.
