READ_CD_FOL
4 0x6D 0x09 N M
ï½¥Outputs information of the L[15:0]={M, N}^th folder in the file system
analysis result.
(For L, Please set up L between file information acquirable numbers
[1st-2nd byte of 'REDA_CD_FONUM'] from 1.)
64 ・The information is output in Little Endian format.
・If L=0 is specified, the command outputs the information on CD volume.
・When file system analysis is not completed, the maximum of specified L
is recorded as information read-out completion.
The acquired information may become invalid when analysis is resumed.

・Output about the present system operation mode.
・Output about the present memory information.
・Output about OFFSET 0x37 of a status buffer.
・Output the CHECK SUM calculation result when IPL download.
・Output a 1st byte= comparison result. When the 1st byte is 0x0, it shows
that comparison result is coincidence. When the 1st byte is 0x1, it shows
that comparison result is disagreement.
・Output a 2nd-3th byte are calculation result and 3th-5th byte are the
value currently written in FLASH ROM.
・Output the information on which stage of media mount went wrong when
ERROR generating.
・1st byte: The state when USB enumeration is outputted.
・2nd byte: The state when SD initialization is outputted.
・10th byte: The state when file system analysis is outputted.
・Other bytes should be disregarded.
・Please read this value only when ERROR=1.
・Also at the time, although a value is read, it is usually the information on
ERROR=0 for which the value was performed at the end.
・Please refer to process information about the details of a read-out value
at the time of a back clause media mount error.
・5th-10th byte = it is 0x04 00 A0 D0 0x04 00 is specified.
・Outputted 1 byte the 5th bit becomes BFULLO status.
・5th-10th byte = it is 0x2E 0x8F 0x00 0x10 0x02 0x00 is specified.
・Outputted internal stop status.
・5th-10th byte = Please refer to the application note.

・Outputted internal FFP status.
・5th-10th byte = it is 0x04 0x02 0xA0 0xD0 0x04 0x00 is specified.
・Bit0 of the reading value outputs the state of the terminal WP of the SD
card.
・Output about a firmware version.
・Output about the image version in Flash.
・1st-2nd byte= model number, 3th-4th= year (lower 2 figures), 5th-8th=
