2.4.2 RESET pin characteristics
The RESET pin input driver uses CMOS technology. It is connected to a permanent pull-up resistor, RPU. EMW3166
contains RC (resistance-capacitance) reset circuit which ensures the module reset accurately when it powers up. If
user need to reset manually, just connect the external control signals to the reset pins directly, but the control signal
should be Open Drain Mode。
