2.16 External Interrupt (~INTR)
The WISMO Quik Q2403 Series provides an external interrupt input (not
managed in the standard AT commands firmware). This input is very
sensitive
and an interrupt is activated on high to low edge. If this signal is not used it
can be left open. If used this input has to be driven by an open collector or an
open drain.
This input is used for instance to power OFF automatically the module.
