mode is enabled, DTR is pulled up and WAKEUP_IN is pulled up, the module can directly enter into sleep
mode. If entering into sleep mode is enabled, DTR is pulled down and WAKEUP_IN is pulled down, there
is a need to pull the DTR pin and the WAKEUP_IN pin up first, and then the module can enter into sleep
mode.
