[7] GPIO: Activity in GPIO

Write ‘1’ to enable interrupt signal from GPIO

Write ‘0’ to disable interrupt signal from GPIO

[6] PWM: Any channel of PWM has completed the programmed sequence

Write ‘1’ to enable interrupt signal from PWM

Write ‘0’ to disable interrupt signal from PWM

[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’

Write ‘1’ to enable interrupt signal from calibration/tuning event

Write ‘0’ to disable interrupt signal from calibration/tuning event

[3] EOC: End of calibration

Write ‘1’ to enable interrupt signal from end of calibration event

Write ‘0’ to disable interrupt signal from end of calibration event

[2] TOUCH: Touchkey event

System should access touch detection register when this interrupt is received.

Touch interrupt source needs to be enabled to activate key filter data.

Write ‘1’ to enable interrupt signal from touch event

Write ‘0’ to disable interrupt signal from touch event

[1] PROX: Proximity sensor event

Write ‘1’ to enable interrupt signal from proximity sensor

[0] RESERVED

Write ‘0’ to disable interrupt signal from proximity sensor
