Similarly, this feature can be used for any mode switching. After the module processes the current mode event, it will
automatically enter the new mode within 1ms; thus saving the user from the work of querying AUX and achieving the
purpose of fast switching ;
For example, switch from transmitting mode to receiving mode; the user MCU can also go to sleep in advance before
mode switching, and use the external interrupt function to obtain AUX changes, so as to perform mode switching.
