3.7. Reset
The RESET_N pin can be used to reset the module. The module can be reset by pulling the RESET_N
pin 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 8: Pin Description of RESET_N
The recommended circuit is similar to the PWRKEY control circuit. An open drain/collector driver or button
can be used to control the RESET_N.
