Browsing this flag on completion of auto tuning allows you to check whether
automatic backup was completed normally or failed.
The write failure flag (b11 to b15) turns off on normal completion of write on the
corresponding channel.
After checking the write flag, always set 0 (OFF) to Automatic backup setting after
auto tuning of PID constants (buffer memory address: 3F , 5F , 7F , 9F ).

If auto tuning is executed while 1 (ON) is set, even if internal processing of auto
tuning is completed and PID constant is stored, Auto tuning status (Xn4 to Xn7)
does not turn OFF and auto tuning is not completed.
