Data input format + number of data to write in bytes
Number of data to write
D" or "d" shows that this field is
Dmmmm
for the number of data to write.
Capital "D" indicates that the
or
data is in ASCII, lower-case "d"
indicates the data is in HEX.
dmmmm
Specify the length of data in
bytes with the number(mmmm)
that comes after "D" or "d".
Data array to write
Data array to write
n
Parameters from here can be specified in any order.
Parameters related to specifying block to start writing (omissible)
Specify block to start writing
wsb:
Specifies the number of bytes for the next parameter "n: data array to write".
This portion should be written in bytes, so the number specified for this field
does not change regardless of data format, whether ASCII or HEX.
Valid range：FeliCa Lite/FeliCa Lite-S(a＝4)："0～224"
Note: Command error occurs if you specify a value that exceeds the
maximum.
Specify 0 if the data of clutch pad is not specified, and do not specify
anything for the next [n:Write Data] except for a comma only at the end.
Specify 0 if parameters related to NFC(NDEF) are used, and do not specify
anything for the next [n:Write Data] except for a comma only at the end.
The character code and maximum number of characters depends on the data
input/output format (ASCII/HEX) as below:
Range of available character codes : (00H)～(FFH)
Valid number of characters：
ASCII
FeliCa Lite/FeliCa Lite-S(a＝4): 0～224 characters
1 character as a step can be specified.
Range of available character codes:
0(30H)～9(39H),A(41H)～F(46H)
HEX Valid number of characters：
FeliCa Lite/FeliCa Lite-S(a＝4): 0～448 characters
Specify it with the multiples of 2 digits.
Specifies the block to start writing the data. The 0
omitted. Block is a unit to write to user memory. The following values in the
table are allowed based on the type of inlets. A maximum up to a 2-digit
decimal can be specified, but a parameter error occurs if it exceeds the
maximum amount for the specified inlet (14 and above). See the following
table.
