GT911 interfaces with the host via 6 pins: VDD, GND, SCL, SDA, INT and RESET.
The INT pin of the host can be rising/falling-edge Triggered. In addition, when INT is in input state, the host
should set INT to be floating, with no internal pull-up or pull-down; the host controls the RESET pin of the GT911
by outputting high or low level. To ensure reliable reset, it is recommended that RESET pin outputs low for longer
than 100μs.
