Parity input

No ......

You need to look at the program number in the binary form

0000 zero

0001 one

0010 two

0011 three

0100 four

0101 five

0110 six

0111 seven

1000 eight

Etc.

Then you need to count number of bits that are set in each case. Parity is set in accordance to that.

For example value seven has 3 bits set

Three is an odd number so value of parity would need to be set according to that and chosen parity method (even/odd).

If using even parity, parity bit would need need to be set to 1 so that total number of all bits is even (including bits in PGNO and the parity bit itself).
