Data input format + number of data to write in bytes
"D" or "d" shows that this field is
for specifying the number of data
to write.
Capital "D" indicates that the
data is in ASCII, lower-case "d"
indicates the write data is in HEX.
Specify the length of data in bytes
with the number(mmmm) that
comes after "D" or "d".
in bytes, so the number specified for this field will not
change regardless of data format, whether ASCII or
HEX.
Specify 0 if there is no data to write to user memory,
in which case specify nothing but the comma for the
succeeding “n: data array to write”.
Data array to write
This parameter is used when the user data is set by using
free format or when there is no user data.
The character code and maximum number of characters
varies depending on the data input/output format (ASCII/
HEX) as below:
ASCII Range of available character codes :(00H) -
(FFH)
See “Mapping table of IC chip type, number
of blocks and total capacity” for the valid
number of characters. It can be specified
by unit of 1 character, so it is the same as
maximum number of bytes allowed for each
IC chip.
n Data array to write
HEX Range of available character codes : 0(30H)
~ 9(39H),A(41H) ~ F(46H)
Specify digits with multiples of 2. The
number of valid characters would be twice
the number of characters available for the
maximum number of bytes for each IC chip,
mentioned in "Mapping table of IC chip type,
number of blocks and total capacity".
Specifying NFC(NDEF) format
NFC: Specify this parameter when you set data in NDEF(NFC Data Exchange Format)
format stipulated by NFC forum.
Valid
range：
1 ~ 6,f
[When setting NFC(NDEF) format user data]
1: user data is regarded as URI format.
2: user data is regarded as TEXT format.
3: user data is regarded as smart poster format.
4: user data is regarded as handover (Bluetooth) format.
5: user data is regarded as handover (Wi-Fi) format.
6: user data is regarded as handover (mixture of Bluetooth/Wi-Fi) format.
[When setting free format user data]
f: User data is written as a free format NDEF message.
* Of a case and the user data that user data is not NDEF form when there is not it, this
designation is unnecessary.
