3.2.2.2 Restart PLSx3 Using EMERG_RST
The EMERG_RST signal is internally connected to the baseband processor. A low level >2
00ms sets the processor and all signals to the reset states, and thus restart the module.
Please note that if the EMERG_RST signal is not released, i.e., changed from low to high, after
a restart, the module will be repeatedly restarted. When the timer of the EMERG_RST signal
is more than 8000ms, the module will be switched off directly.
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
information stored in the volatile memory. Therefore, this procedure is intended only for use in
case of emergency, e.g. if PLSx3 does not respond, if reset or shutdown via AT command
fails.
