R/W Description
R/W The highest-order byte (MSB) of the 4-byte input to the
CD-ROM decoder
The CD-ROM decoder has a 4-byte wide data window
or set of registers for data input. The data input to these
registers is handled as a data stream. The amount of
data for one sector is 2352 bytes.
21.3.53 CD-ROM Decoder Stream Data Input Register (STRMDIN1)
STRMDIN1 indicates the next 1 byte, in order from STRMDIN0, of the 4-byte input to the CD-
ROM decoder.
