20 / 55 page  Interrupt controller module STMPE821 20/55 INT_CTRL Interrupt control register Address: 0x08 Type: R/W Reset: 0x00 Description: This register is used to enable control the polarity, edge/level and enabling of the interrupt system.device 7 654 3210 POLARITY TYPE INT_EN [7:3] RESERVED [2] POLARITY: '0' for active low '1' for active high For active low operation, the INT pin should be externally pulled high (up to 3.3 V, but ≤VIO). The INT pin will be pulled to GND when there is a pending interrupt. For active high operation, the INT pin should be externally pulled to GND. In this mode, the INT pin will be pulled to VCC by the device when there is a pending interrupt. [1] TYPE: '0' for level trigger '1' for edge trigger (pulse width is 200 nS) [0] INT_EN: '0' to disable all interrupt '1' to enable all interrupt |
