The AP_READY pin can be used by the module to detect if the host is woken up and can
be configured for high level detection or low level detection.
W_DISABLE#:
Flight mode control (this function is under development), when the CLM920 TD3
module W_DISABLE# signal is pulled low, the module RF function can be turned off, the
module can enter the flight mode, and the module can be turned on to open the module RF
function. It can also be set to flight mode by AT+CFUN. For details, please refer to CLM920
