This register is used to enable control the polarity, edge/level and enabling of the
interrupt system.device
'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 ≤ V
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 V
'0' for level trigger
'1' for edge trigger (pulse width is 200 nS)
'0' to disable all interrupt
