[7] GPIO: Activity in GPIO
Read ‘1’ if GPIO event occurs
Write ‘1’ to clear the interrupt status
[6] PWM: Any channel of PWM has completed the programmed sequence
Read ‘1’ if PWM event occurs
Write ‘1’ to clear the interrupt status
[5] Device wake up from SLEEP or HIBERNATE mode
Read ‘1’ if wake-up event occurs
Write ‘1’ to clear the interrupt status
[4] ENV: Possible drastic/abnormal environmental changes that requires attention from system
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
[3] EOC: End of calibration
Read ‘1’ if the host-triggered calibration has completed
Write ‘1’ to clear the interrupt status
[2] TOUCH: Touch-key event
Read ‘1’ if touch is detected
Write ‘1’ to clear the interrupt status
[1] RE2: Ratio engine 2 event
Read ‘1’ if ratio engine 2 detects a touch or data is ready
Write ‘1’ to clear the interrupt status
[0] RE1: Ratio engine 1 event
Read ‘1’ if ratio engine 1 detects a touch or data is ready
Write ‘1’ to clear the interrupt status
