Audio Output Result drives status change. Enabling this bit causes a change in the audio output result register (either
LRSL or RRSL) to make the INT pin active (if the INT pin is enabled with STAE.) Reading the status register clears
Status change output polarity (INT pin polarity)
Status change output enable. The INT pin is enabled or disabled by this bit. When enabled, the INT pin indicates any
change in the status register (64H). Reading the status register clears the INT pin.
