1: Indicates that the modem receive-data DMA overran.
This bit is cleared when “1” is written to it.
1: Indicates that the modem transmit-data DMA underran.
This bit is cleared when “1” is written to it.
1: Indicates that the audio receive-data DMA overran.
This bit is cleared when “1” is written to it.
1: Indicates that the audio LFE transmit-data DMA underran.
This bit is cleared when “1” is written to it.
1: Indicates that the audio center transmit-data DMA underran.
This bit is cleared when “1” is written to it.
1: Indicates that the audio surround L&R transmit-data DMA
underran.
This bit is cleared when “1” is written to it.
1: Indicates that the audio PCM L&R transmit-data DMA underran.
This bit is cleared when “1” is written to it.
1: Indicates that the incoming slot 12 bit[0] is ‘1’ (the modem CODEC
GPIO interrupt).
This bit is cleared if “1” is written to it while the incoming slot 12 bit[0]
is ‘0’.
