SET_TESTU_MODE2 4
0x60 0x18 0x0C N
・Specify the operation for the second-time Test Unit Ready command in USB
memory mount operation.
・Select N from the following. Any other settings will not accept the command.
N= 0x00 : Retry is performed according to the setting value of a SET_RETVAL
command.
N= 0x01 : Retry is performed infinitely.
N= 0x02 : Cancels infinite retry of N=0x01 setting.
・Initial setting is N= 0x00 (Retry is performed according to the setting value of a
SET_RETVAL command.)
SET_TOUT_TUR2
6 0x60 0x18 0x0D 0x00 ・Specify the wait time after the second-time Test Unit Ready command in USB
memory mount operation.
・Setting value [value of SET_TOUT_TUR2] x 2 x [value of SET_RETVAL]
becomes the wait time.
・Specify the setting value to the 5 - 6th byte with a little endian.
・Initial setting is N=0xFF (255 x 2 x 375 =191,250msec).
・Specify N within the range from 0x00 to 0xFFFF
SET_EMP_DIR
4 0x60 0x1A N 0x00 ・At the time of the FAT analysis, A number isn't given to folders which the file
which can reproduce is not in through.
・Select N at the 3^rd byte from the following. Any other setting is considered to
specify N=0x01.
N=0x00 ; A number is assigned in folders as well which the file which can
reproduce is not in through.
N=0x01 ; A number isn’t assigned in folders as well which the file which can
reproduce is not in through.
・Initial value is N= 0x00.
SEL_IRPTO
4 0x60 0x1B N 0x00 ・Specify the mode of IRPTO signal output condition.
・In variable interruption mode, IRPTO is unified output by two or more status
change. Master microcomputer can select the status.
・In fixed interruption mode, IRPTO is output by single status change according
to system mode.
・Select N from the following. Any other setting is considered to specify N=0x00.
N=0x00: Variable interruption mode
N=0x01: Fixed interruption mode
・Initial value is N= 0x00(Variable interruption mode)

・MASK is done from the movement of IRPTO toward each bit of the status
register STATUS1 (Offset : 0x0000).
MASK is done with bit which 'H' was set up to from the interruption factor of
IRPTO
Initial value is 0x7A.
・Refer to 6.4.12 for the details of the movement.
・MASK is done from the movement of IRPTO toward each bit of the status
register STATUS1 (Offset : 0x0002).
MASK is done with bit which 'H' was set up to from the interruption factor of
IRPTO
Initial value is 0x3F.
・Refer to 6.4.12 for the details of the movement.
・MASK is done from the movement of IRPTO toward each bit of the status
register STATUS1 (Offset : 0x0022).
MASK is done with bit which 'H' was set up to from the interruption factor of
IRPTO
Initial value is 0x4E.
・Refer to 6.4.12 for the details of the movement.
・MASK is done from the movement of IRPTO toward each bit of the status
register STATUS1 (Offset : 0x002F).
MASK is done with bit which 'H' was set up to from the interruption factor of
IRPTO
Initial value is 0x75.
・Refer to 6.4.12 for the details of the movement.
・MASK is done from the movement of IRPTO toward each bit of the status
register STATUS1 (Offset : 0x0037).
MASK is done with bit which 'H' was set up to from the interruption factor of
IRPTO
Initial value is 0xF8.
・Refer to 6.4.12 for the details of the movement.
・When folder and file are sorted. It is configured whether it cases sensitivity of
the alphabet.
When it was configured without a distinction. It becomes only alphabet ("a" - "z"
and "A" - "Z") that it is equated.
・Select N at the 4^rd byte from the following. Any other setting is considered to
specify N=0x01.
N=0x00 ; Alphabet doesn't case sensitivity.
N=0x01 ; Alphabet cases sensitivity.
・Initial value is N= 0x00.
