value of P12.20–P12.22 will
renew automatically. These
parameters are basic
parameters controlled by
vectors which directly impact
the features.
When P00.15=1, the set value
of P12.23 can be updated
through autotuning
automatically, and there is no
need to change the value of
P12.23; when P00.15=2, the
set value of P12.23 cannot be
updated through autotuning,
please account and update
the value of P12.23.
Note: Users cannot modify
the parameters freely.
