Randomizing Circuit Input Switching signal
0/1 Balanced Error Detection Clear signal
Simple Random Number Evaluation Measurement Clear signal
Randomizing Circuit Error Clear signal
If the fault threshold input signal “seed” circuit output 0/1 balance
was judged to have been disrupted, the recommended value of
the signal wire that inputs the threshold is the decimal value 13
(0xD hexadecimal)
