6.3.8 Pushbutton Long Press Function

The pushbutton function implemented through the TS/MR pin enables the device to enter factory mode after a long button press. When VIN is present, holding the TS/MR pin LOW for a duration tLPRESS initiates factory mode entry. After this duration, removing VIN places the device into factory mode. When VIN is present, toggling the CE pin restarts the long press timer. Connect a valid VIN to wake the device from factory mode. The pushbutton cannot be used to wake the device from factory mode.
