4 0x62 0x01 0x03 0x00 ・This command analyzes the full path (within the memory) of the entry
pointed by the memory browsing cursor.
10 0x62 0x01 0x04 0x00 ・This command starts playing the file specified by the access data.
・If the access data does not specify a playable file, the LSI searches the
first tune in the device and stops.
・The position of the memory browsing cursor does not change.
・Set the access data at the 5^th-10^th bytes. *2
4 0x62 0x02 0x01 N ・This command moves the memory browsing cursor from the current
position to the position N ahead in the sort order.
・The analysis is performed for the information of the entries specified by
the SET_BROWSE_NUM command, starting from the move destination.
After the analysis is completed, the LSI writes the result to the status
register.
・If there are less than N files after the current memory browsing cursor
position in the folder, the cursor position goes to the end of the folder.
・If the sort function (SET_SORT) is OFF, the cursor moves in the FAT
order.
4 0x62 0x02 0x02 N ・This command moves the memory browsing cursor from the current
position to the position N backward in the sort order.
・The analysis is performed for the information of the entries specified by
the SET_BROWSE_NUM command, starting from the move destination.
After the analysis is completed, the LSI writes the result to the status
register.
・If there are less than N files from the top of the folder to the current
memory browsing cursor position, the cursor position goes to the top of
the folder.
・If the sort function (SET_SORT) is OFF, the cursor moves in the FAT
order.
4 0x62 0x02 0x03 0x00 ・This command moves the memory browsing cursor to a higher-level
folder.
・After moving, the LSI analyzes the folder.
・If the cursor is in the highest layer (root), nothing will be done.
4 0x62 0x02 0x04 0x00 ・This command selects the lower-level holder pointed by the memory
browsing cursor to move. After moving, the LSI analyzes the folder.
・When a folder is selected, the LSI starts analyzing it.
・When a file is selected, the LSI does not accept the command.
・If the cursor selects the folder in the lowest layer, nothing will be done.
4 0x62 0x02 0x05 0x00 ・This command moves the memory browsing cursor to the top of the root
folder.
・After moving, the LSI analyzes the folder.
4 0x62 0x02 0x06 0x00 ・This command moves the memory browsing cursor to the tune being
played.
・After moving, the LSI analyzes the folder.
・During stop or search, the LSI does not accept the command.
10 0x62 0x02 0x07 N ・This command moves the memory browsing cursor to the position
specified by the access data.
・After moving, the LSI starts analyzing at this position.
・Set the access data at the 5^th-10^th bytes. *2
・Select the operation after moving with N in the 4^th byte. Select N from
the following. Any setting other than N=0x00 will be considered to
specify N=0x01.
N=0x00: Only moves the cursor and analyzes.
N=0x01: If moving to a file, starts playing it.
