21.3.51 CD-ROM Decoder Stream Data Input Register (STRMDIN0)
The CD-ROM decoder stream data input register (STRDMIN0) holds the higher 2 bytes (from
MSB) of the 4 bytes of data that is to be input to the CD-ROM decoder.

R/W Description
R/W Indicate the higher 2 bytes (from MSB) of the 4-bytes of
data that is to be input to the CD-ROM decoder.
The CD-ROM decoder has a 4-byte wide data window
as a data input register to handle the data input to this
register as a stream data. The amount of data for one
sector is 2352 bytes.
21.3.52 CD-ROM Decoder Stream Data Input Register (STRMDIN2)
The CD-ROM decoder stream data input register (STRDMIN2) holds the lower 2 bytes (from
LSB) of the 4 bytes of data that is to be input to the CD-ROM decoder.
