M ・Set the format of the input from CD with N at the 3^rd byte. Select N
from the following. Any other settings will not accept the command.
N=0x00: Inputs in I²S (32 fs) format.
N=0x01: Inputs in I²S (48 fs) format.
N=0x02: Inputs in I²S (64 fs) format.
N=0x04: Inputs in EIAJ (32 fs) format.
N=0x05: Inputs in EIAJ (48 fs) format.
N=0x06: Inputs in EIAJ (64 fs) format.
・Set the sample rate of the input from CD with M at the 4^th byte. Select M
from the following. Any other settings will not accept the command.
M=0x00: 32 kHz, M=0x01: 44.1 kHz, M=0x02: 48 kHz
・Set the bit rate during MP3 encode with L at the 5^th byte. Select L from
the following. Any other settings will not accept the command.
L=0x00: 32 kbps, L=0x01: 64 kbps, L=0x02: 128 kbps
L=0x03: 192 kbps, L=0x04: 256 kbps, L=0x05: 320 kbps
・By default, N=0x05: "EIAJ (48 fs)", M=0x01: "44.1 kHz", and L=0x02:
"128 kbps" are set.
・Do this setting before opening the encode file (before START_ENC).
Any change after opening the file will not be accepted.
・Embed 6^th to 8^th bytes with 0x00.
M ・This command sets ID3 V2.3 TAG to be written during encode.
・Up to 64 bytes of TAG can be written to TITLE, ARTIST, ALBUM, and
GENRE.
・Set the TAG type with N at the 3^rd byte. Select N from the following.
Any other settings will not accept the command.
N=0x00: TITLE, N=0x01: ARTIST,
N=0x02: ALBUM, N=0x03: GENRE
・Set the TAG character code with M at the 4^th byte. Select M from the
following. Any other settings will not accept the command.
M=0x00: ISO-8859-1 or no specification (Native [Shift-JIS etc.])
M=0x01: UTF-16 (Unicode with BOM)
・When specifying M=0x01, BOM(U+FEFF) is required to identify Endian.
・Set the data at the 5^th-68^th bytes in the left aligned format. If the data to
be written is less than 64 bytes, embed the empty bytes with 0x00s.
・Do this setting before opening the encode file (before
START_ENCODE). Any change after opening the file will not be
accepted.
・When closing the file (STOP_ENCODE), this setting is cleared.
4 0x65 0x00 N M ・This command enables CD-ROM input.
・Set the ECC retry count with N at the 3^rd byte. Specify N within the
range from 0x00 to 0x0F. Any other settings will not accept the
command.
・When N=0x00, error correction is performed only for EDC. When
N=0x01 to 0x0F, the LSI executes EDC and then executes ECC as many
times as specified (retry specification).
・Set the format of the input from CD with M at the 4^th byte. Select M
from the following. Any other settings will not accept the command.
M=0x00: Inputs in I²S (32fs) format.
M=0x01: Inputs in I²S (48fs) format.
M=0x02: Inputs in I²S (64fs) format.
M=0x04: Inputs in EIAJ (32fs) format.
M=0x05: Inputs in EIAJ (48fs) format.
M=0x06: Inputs in EIAJ (64fs) format.
・By default, N=0x03: "ECC retry count 3" and M=0x05: "Inputs in EIAJ
(48fs) format" are set.
・By default, CD-ROM input is disabled.
4 0x65 0x01 0x01 0x00 ・This command disables CD-ROM input.
・The command cancels the SEEK request (necessary LBN request).
・When the LSI is analyzing the CD-ROM file system, the command stops
analysis.
