3.7. Reset
The module can be reset by driving the RESET_N low for at least 100 ms and then releasing it. The
RESET_N signal is sensitive to interference, so it is recommended to route the trace as short as possible
and surround it with ground.
Table 10: Pin Definition of RESET
The recommended circuit is equal to the PWRKEY control circuit. An open drain/collector driver or button
can be used to control the RESET_N.
