bytes
Status
1st byte
2nd byte
READ_BUFF
0x5E
OFFSET
Optional
· The command outputs the desired bytes of
data from the OFFSET position specified in the
status register map.
· Since the status register functions as a ring
buffer of 0x00-0x7F, the master returns to 0x00
after OFFSET position 0x7F during data read.
READ_STATUS
0x5F
0x00
5
· This command outputs the data of OFFSET
0x00-0x04 in the status buffer.
READ_PLAY_INFO
0x01
6
· This command outputs the data of OFFSET
0x0A-0x0F in the status buffer.
READ_VOL
0x02
1
· This command outputs the data of OFFSET
0x05 in the status buffer.
READ_EQ
0x03
1
· This command outputs the data of OFFSET
0x06 in the status buffer.
READ_ID3_TITLE
0x04
64
· This command outputs the data of
WMATag/ID3Tag Title. *1
READ_ID3_ARTIST
0x05
64
· This command outputs the data of
WMATag/ID3Tag Artist.*1
READ_ID3_ALBUM
0x06
64
· This command outputs the data of
WMATag/ID3Tag Album.*1
READ_FILE_NAME
0x07

· This command outputs the data of
playing AAC/WMA/MP3 file name. see VI.1.4
READ_FOLDER_NAME
0x08

· This command outputs the data of
folder name includes playing AAC/WMA/MP3
file. see VI.1.4
READ_RESUME_INFO

· This command outputs the data of Firmware
version.
READ_FILE_SIZE
0x11
4
·
The size of a specified file of the File Read
function is acquired. It outputs with LittleEndian.
·

and 0xFF" is output.
READ_FILE_DATA
0x12
96
·
The file data of a specified file of the File Read
function is read.
·
The 92byte data reading is possible by one
time.
·
Four head bytes are file offsets. It outputs it
with LittleEndian.
READ_LUN
0x17
1
·
In case of AUTO detection mode of LUN, LUN
of mounted USB memory can be read.
·
If LUN is specified using the "SET_LUN"
command, specified LUN of mounted USB
memory can be read. But if failed to mount, 0xFF
is read.
·
Attention) When memory connected to
multi-card reader is removed or re-inserted, LUN
read by this command is NOT correct until mount
of re-inserted media is completed.
READ_LUN_NUM
