Read ‘1’ if GPIO event occurs
Write ‘1’ to clear the interrupt status
Read ‘1’ if PWM event occurs
Write ‘1’ to clear the interrupt status
Read ‘1’ if wake-up event occurs
Write ‘1’ to clear the interrupt status
software. This event includes ‘calibration stuck’ and ‘tuning out of range’. If this bit is set, it is
recommended that the host software initiates an unconditional calibration.
Read ‘1’ if the events occur
Write ‘1’ to clear the interrupt status
Read ‘1’ if the host-triggered calibration has completed
Write ‘1’ to clear the interrupt status
Read ‘1’ if touch is detected
Write ‘1’ to clear the interrupt status
Read ‘1’ if ratio engine 2 detects a touch or data is ready
Write ‘1’ to clear the interrupt status
Read ‘1’ if ratio engine 1 detects a touch or data is ready
