4 0x61 0x0A M N ・When receiving the FOL- command during play, pause, or stop, the LSI
searches the folder N tunes back from the one having the file being
played or paused in the sort order.
・When playing a tune less than N folders from the top in the sort order,
the LSI returns to the first folder. However, when playing a file within the
first folder, the LSI searches the folder across the last tune within the
memory.
・Even if REPEAT or RANDOM is set, the LSI searches the file in the
status where repeat mode is set.
・Search the file chosen at random when RANDOM is set.
・If N=0, the LSI searches the top of the current folder.
・If TAG analysis is enabled, the LSI also performs that analysis.
・After searching, the LSI operates in accordance with the setting in the 3^rd
byte. Select M at the 3^rd byte from the following. Any setting other
than M=0x00 is considered to specify M=0x01.
M=0x00: Stops after search is completed.
M=0x01: Starts playing after search is completed.
・The number of folders to be searched depends on the setting of N in the
4th byte.
46 0x61 0x0B 0x00 0x00 ・This command sets 42-byte data obtained by the
READ_RESUME_INFO command to 5^th-46^th bytes.
・Set the data in ascending order of the offsets obtained by the
READ_RESUME_INFO command.
・After writing the command, the LSI starts resume play.
・If the resume target cannot be searched, the LSI searches the first tune
of in the device and plays.

N=0x01: Outputs using the SPDIF interface
N=0x02: Outputs in I²S (32fs) format.
N=0x03: Outputs in I²S (48fs) format.
N=0x04: Outputs in I²S (64fs) format.
N=0x05: Outputs in EIAJ (32fs) format.
