R/W Description
R/W The higher-order byte (MSB) of the 2-byte 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 are
output sequentially in the output format which is
separately defined. The amount of data for one sector is
2768 bytes. Always read 2768 bytes.
21.3.57 CD-ROM Decoder Stream Data Output Register (STRMDOUT1)
