This read-only status bit is high when the IRQ interrupt is pending.
Writing a logic one to this write-only bit clears the IRQ latch. ACK
always reads as logic zero. Reset clears ACK.
Writing a logic one to this read/write bit disables IRQ interrupt
requests. Reset clears IMASK.
This read/write bit controls the triggering sensitivity of the IRQ pin.
Reset clears MODE.
IRQPUD disconnects the internal pull-up on the IRQ pin.
For More Information On This Product,
1 = IRQ interrupt pending
0 = IRQ interrupt not pending
1 = IRQ interrupt requests disabled
0 = IRQ interrupt requests enabled
1 = IRQ interrupt requests on falling edges and low levels
0 = IRQ interrupt requests on falling edges only
1 = Internal pull-up is disconnected
0 = Internal pull-up is connected between IRQ pin and V
