Audio unit has a 8x64 bytes fifo for pre-fetching and 

staging audio samples. This register provides a watermark value in SWORDs (64B). 

When enable and sample buffer is available audio unit will fetch samples until this FIFO 

is full then it waits until HDMI/DP packet assembler drains the samples to a level less or 

equal the watermark setting then it will start fetching the samples again. 

Default value is 1 cacheline (SW).

Audio unit has a 96x8 bytes fifo for pre-fetching and staging 

audio samples. This register provides a watermark value in DWORDs. When enable and 

sample buffer is available audio unit will fetch samples until this FIFO occupancy is 

above the watermark then it waits until HDMI packet assembler drains the samples to a 

level less or equal the watermark setting then it will start fetching the samples again
