• DISHIFT: Discharge Shift
For QMatrix sensors, specifies how many bits the DILEN field should be shifted before using it to determine the discharge time.
• SYNC: Sync Pin
For QMatrix sensors, specifies that acquisition shall begin when a falling edge is received on the SYNC line.
• SPREAD: Spread Spectrum Sensor Drive
For QMatrix sensors, specifies that spread spectrum sensor drive shall be used.
• DILEN: Discharge Length
For QMatrix sensors, specifies how many burst prescaler clock cycles the CAT should use to discharge the capacitors at the
beginning of a burst sequence.
• MAX: Maximum Count
For QMatrix sensors, specifies how many counts the maximum acquisition should be.
