5. Function Description

5.1 Reset

When the module is powered, AUX outputs low level immediately, conducts hardware self-check and sets the operating mode on the basis
of the user parameters. During the process, the AUX keeps low level. After the process completed, the AUX outputs high level and starts
to work as per the operating mode combined by M1 and M0. Therefore, the user needs to wait the AUX rising edge as the starting point
of module's normal work.
