3.3 Mechanical Buttons
The ATSAMR30M Sensor Board contains two mechanical
buttons:
- Reset button (RS_BTN) connected to the
ATSAMR30M Reset line
- When the RS_BTN button is pressed, the Reset line is driven to ground, which resets the module
- Generic user-configurable button
(USR_BTN)
- When the USR_BTN button is pressed, the I/O line is driven to ground
Note: The PA28 pin connected with USR_BTN can be
used as a wake-up source from the Backup mode of the ATSAMR30M Sensor Board.
