4.2 PERST#
SIM7600E-PCIE can be reset by pulling the PERST# pin down to ground.
The PERST# pin has been pulled up with a 47KΩ resistor to 1.8V internally, so there is no need to pull it up
externally. It is strongly recommended to put a 100nF capacitor and an ESD protection diode close to the
PERST# pin. Please refer to the following figure for the recommended reference circuit.
