FIFO Size — RO (Input stream), R/W (Output stream): Indicates the  
maximum number of bytes that could be fetched by the controller at one  
time. This is the maximum number of bytes that may have been DMA’d  
into memory but not yet transmitted on the link, and is also the maximum  
possible value that the PICB count will increase by at one time.  
The value in this field is different for input and output streams. It is also  
dependent on the Bits per Samples setting for the corresponding stream.  
Following are the values read/written from/to this register for input and  
output streams, and for non-padded and padded bit formats:  
Output Stream R/W value:

NOTES:  
1.  
2.  
All other values not listed are not supported.  
When the output stream is programmed to an unsupported size,  
the hardware sets itself to the default value (BFh).  
Software must read the bit field to test if the value is supported  
after setting the bit field.

NOTE: The default value is different for input and output streams, and  
reflects the default state of the BITS fields (in Stream Descriptor  
Format registers) for the corresponding stream.
