It is strongly recommended to control this EMERG_RST line with an open collector transistor
or an open drain field-effect transistor.
Caution: Use the EMERG_RST line only when, due to serious problems, the software is not
responding for more than 5 seconds. Pulling the EMERG_RST line causes the loss of all infor-
mation stored in the volatile memory. Therefore, this procedure is intended only for use in case
of emergency, e.g. if EXSx2-W does not respond, if reset or shutdown via AT command fails.
