1. Readout Register Interrupt_Status

2. Write back the readout value in (1) to Interrupt_Status - this automatically resets all readout interrupts (and no

interrupts can be lost)

Interrupts can be enabled / disabled individually by the Interrupt_Mask register (if an interrupt is masked, it will not pull-

down the pin INT/AUDIO_IN):
