b7 b6 b5 b4
0 0 0 0 = reserved
0 0 0 0 = reserved
0 0 0 0 = reserved
Parameters
0 0 0 0 = reserved

Define RFID Write Parameters
Command Name
Defines the auto write parameters for the AutoRun command.
Description
- write field [0 - 3], 1 byte, hexadecimal
- start address [12 - 127], see Appendix C, base 64
- write size [1 - 32], see Appendix C, base 64. Sum of start address and write size must
not exceed 128.
- write string (compressed with regard to the more limited Code 128 encoding scheme
[0 - 127] where a single ASCII character can be encoded as up to 3 bytes, see
Appendix D)
The write string uses hex values of extended ASCII characters [0 - 55] compressed as
follows:
1.
4-48
The first extended ASCII character in the string is always encoded into 2 bytes ():
- the high-level nibble of the hex value of the extended ASCII character is encoded
into the low-level nibble of the first byte (the high-level nibble is always equal to 0)
- the low-level nibble of the hex value of the extended ASCII character is encoded
into the low-level nibble of the second byte (the high-level nibble is always equal
to 0)
