·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 the total of LUN of the USB memory which is connected now.
·Read LUN specified by the "SET_LUN" command.
In not setting up, 0xFF is read.
・The condition of the status register made the target of the dimension of
IRPTO is outputted.
5byte data is outputted in the order STATUS1 (Offset : 0x000)、STATUS3
(Offset : 0x002) 、 BROWSESTAT (Offset : 0x022) 、 FIOSTAT (Offset :
0x02F)、MEMINFO (Offset : 0x037), and 5byte and outputs the flag which
shows bit which is the dimension of IRPTO. As for the flag of the interrupted
dimension, MASK isn't done by MASK configuration.
・ The consequence of Test Unit Ready of each confirmed LUN by
「AUTO_RECOG_LUN」 or 「RECOG_LUN」is read out.
・When Test Unit Ready is OK, output 1.
・When Test Unit Ready is NG, output 0.
・It is outputted about OFFSET 0x31-0x32 of the status buffer.
・LUN_READY_RENEW flag is cleared by the read of this command.
・MASK configuration from the dimension of IRPTO can be read out each bit of
the status register STATUS1 (Offset : 0x00).
‘H' bit is MASK from the IRPTO dimension.
・MASK configuration from the dimension of IRPTO can be read out each bit of
the status register STATUS1 (Offset : 0x02).
‘H' bit is MASK from the IRPTO dimension.
・MASK configuration from the dimension of IRPTO can be read out each bit of
the status register STATUS1 (Offset : 0x22).
‘H' bit is MASK from the IRPTO dimension.
・MASK configuration from the dimension of IRPTO can be read out each bit of
the status register STATUS1 (Offset : 0x2F).
‘H' bit is MASK from the IRPTO dimension.
・MASK configuration from the dimension of IRPTO can be read out each bit of
the status register STATUS1 (Offset : 0x37).
‘H' bit is MASK from the IRPTO dimension.
・Output the state of reproduction stop processing.
・When you send command accompanied by reproduction operation after
STOP command ,check the completion of stop processing with this command
in advance.
・1st byte outputs the state of stop processing.
1st byte=0x00: stop processing is completed. The command accompanied by
reproduction operation can be executed.
1st byte=other than 0x00: stop processing or reproduction processing is
running .
・2nd-4th byte outputs other internal processing state.
・Output about the browsing analysis status in a memory.
・Output about OFFSET 0x22- of a status buffer.
・Output about the cursor position number of browsing in a memory.
・Output about OFFSET 0x23-0x26 of a status buffer.
・Output about the number of entries in the folder in which the cursor of
browsing in a memory exists, and the number of classes.
・Output about OFFSET 0x27-0x2D of a status buffer.
・Outputs the information on the folder where the entry being pointed by the
memory browsing cursor resides.
・See 6.4.7 for the output format.
・Outputs the information on the Nth entry ahead from the one being pointed by
the memory browsing cursor.
・Specify N at the 4^th byte. Specify N in the range from 0x00 to 0x10.
・See 17. File browsing within memory for the output format.
