Note: 1. Check or uncheck the boxes won’t change the chip state machine, INTRb will only indicate the checked detections. 2. INTRb is the NOR of flags and those flags need to be cleared manually by writing 0x0 to the corresponded _FLGs. 3. The last input rise edge to INTRb negative edge is 2.15us but not exact 4 Fpfd cycles (Fpfd = 2MHz that is T = 500ns period) due to internal delay.
