Indicate 2 bytes that are to be output from the CD-ROM 
decoder. 
The CD-ROM decoder has a 2-byte wide data window 
or set of registers for the output of decoded data. Every 
time the relevant register is accessed, further data of 
access size are output sequentially in the output format 
that is separately defined. The amount of data for one 
sector is 2768 bytes. Always read 2768 bytes.
