Channel 0 PID Control enable signal
When this signal is set on, the PID
control enable bit of this channel
are opened; the PID control process
is closed when reset these bits. All
channels are closed when the power
is on.

Channel 0 Self-study enable signal
Under the condition of the channel
enable bit is set on, set on the self-
study bit to start self-study; when
the self-study bit is 0, it means the
self-study process end or close.
