reset requirement on BL654 (nRF52833 based module)

[ouhui93]

Hi All,

I would like to know if the reset can configured to trigger by "failling edge" rather than "rsing edge" of the reset pin / configured pin?

Per the datasheet from both Ezurio / Nordic, both mentioned some "hold time" is required before reset will take place. 

Is it possible to configure so it will reset whenever the pin is low / trigger by failling edge of the pin? Is this behaviour desgined by hardware?

Hi Raymond,

For the nRF52833, the reset pin (pin reset) behavior is determined by hardware and is not configurable to trigger on a specific edge (falling or rising). a pin reset is generated when the physical reset pin on the device is held low (active low), and the device will reset after the pin has been held low for a required minimum time. This is a hardware-defined behavior and cannot be changed.
