2.3.1.2 Guidelines for PWR_ON layout design
The power-on circuit (PWR_ON) requires careful layout since it is the sensitive input available to switch on
and switch off the SARA-R4/N4 series modules. It is required to ensure that the voltage level is well defined
during operation and no transient noise is coupled on this line, otherwise the module might detect a
spurious power-on request.
