Figure 23.15 shows the format of the output data stream produced by CD-ROM decoding. 

A 2-byte-wide window register STRMDOUT0 is provided for the output. When this window 
register is accessed after decoding of a CD-ROM sector has finished, the bytes of data are output 
in order from the sync code.
