0xX RW Configure Evaluation Mode
Mode Description
THRES Threshold comparison is used to evaluate sensor result
SLIDINGWIN Sliding window is used to evaluate sensor result
STEPDET Step detection is used to evaluate sensor result
X RW Enable Inversion of Result
0xX RW Enable Storing of Sensor Sample in Result Buffer
Mode Description
DISABLE Nothing will be stored in the result buffer.
DATA The sensor sample data will be stored in the result buffer.
DATASRC The data source (i.e., the channel) will be stored alongside the sensor
sample data.
X RW Send Result to Decoder
X RW Select Mode for Threshold Comparison
Mode Description
LESS Comparison evaluates to 1 if sensor data is less than COMPTHRES.
GE Comparison evaluates to 1 if sensor data is greater than or equal to
COMPTHRES.
