XOR function
As shown in Fig. 5-20 and 5-21, this function reflects the results of an exclusive logic (XOR)
function processing for multiple inputs (I
n
) in the function output (O
n
).

Self-hold function
As shown in Fig. 5-22 and 5-23, this function is comprised of a hold input (IH
n
), a trigger input (IT
n
),
and a functional output (O
n
), and reflects the results of self-holding processing by the hold input
and trigger input in the output.
