Position of the touch in ratio engine sensors
Movement of the touch location as a function of POS1 – POS0, where POS1 is current position
and POS0 is position before.
Delay between current and previous samples in unit of time
This bit indicates the status of the finger
‘1’ indicates a finger touches the slider/wheel
‘0’ indicates no touch is detected
Ratio Engine generates an interrupt on the event of transition from touch to no touch. When
host receive the interrupt, it needs to check this bit to verify the presence of the finger. When
touch is detected, the data in RE1_POS and RE2_POS are valid, otherwise it means finger is
lifted up
