IL programming language
LD, FBD programming language
Function:
PARITY_ *
instruction to check the input bit string is
. 1
the number of bits is odd or
even number, an odd number if the output is
FALSE
, is even if the output is
TRUE, PARITY_

When the input bit string as a number of
bits is an odd number, the output
is FALSE; is a number of bits of an even number
of time ( including 0 th to 1 -bit ) , output
is TRUE
