3.10 Module status indication
The C100QM/C10QM module provides a pin as a working status indicator for the module.
This pin can be used to connect to a GPIO or LED with pull-up. It is used to indicate the
power-on status of the module. The drive current should be less than 0.8mA. The STATUS
pin will output a low level and the rest will be in a high impedance state.
