NOTES
1. SLOW_FILTER_EN, WHICH IS THE NAME OF THE OUTPUT OF COMPARATOR 3, IS SET AND SW1 IS CLOSED WHEN |STAGEx_SF_WORD0 – CDC VALUE|
EXCEEDS THE VALUE PROGRAMMED IN THE SLOW_FILTER_UPDATE_LVL REGISTER PROVIDING PROXIMITY IS NOT SET.
2. PROXIMITY 1 IS SET WHEN |STAGEx_FF_WORD0 – STAGEx_FF_WORD3| EXCEEDS THE VALUE PROGRAMMED IN THE
PROXIMITY_DETECTION_RATE REGISTER.
3. PROXIMITY 2 IS SET WHEN |AVERAGE – AMBIENT| EXCEEDS THE VALUE PROGRAMMED IN THE PROXIMITY_RECAL_LVL REGISTER.
4. DESCRIPTION OF COMPARATOR FUNCTIONS:
COMPARATOR 1: USED TO DETECT WHEN A USER IS APPROACHING OR LEAVING A SENSOR.
COMPARATOR 2: USED TO DETECT WHEN A USER IS HOVERING OVER A SENSOR OR APPROACHING A SENSOR VERY SLOWLY.
ALSO USED TO DETECT IF THE SENSOR AMBIENT LEVEL HAS CHANGED AS A RESULT OF THE USER INTERACTION.
FOR EXAMPLE, HUMIDITY OR DIRT LEFT BEHIND ON SENSOR.
COMPARATOR 3: USED TO ENABLE THE SLOW FILTER UPDATE RATE. THE SLOW FILTER IS UPDATED WHEN SLOW_FILTER_EN IS SET AND
PROXIMITY IS NOT SET.
