Incorrect reading returned by Boot Count Sensor
Incorrect reading returned by Boot Count Sensor

    -Fixed mask to ignore bit bit 0 of uint16_t
     event_status returned by readSensorData.
     Previous mask had an extra charactor which
     allowed it to incorrectly pass the high
     order bit of the event status back to the caller.
