27 / 85 page ![]() STMPE16M31, STMPE24M31 System controller Doc ID 16174 Rev 4 27/85 INT_STA Interrupt status register Address: 0x08 Type: R/W Reset: 0x00 Description: This register holds interrupt status from each event. 76 543 210 GPIO PWM WAKEUP ENV EOC TOUCH RE2 RE1 RW RW RW RW RW RW RW RW 00 000 000 [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 Obsolete Product(s) - Obsolete Product(s) |
