2. To check the write results, read the user memory again, see "Read user memory
[Read] / [Auto-Read]" programming example.
Read user memory 40bytes [Read]
Transponder IC: NXP SLIX (1 block = 4bytes)
Number of memory blocks: 10 blocks = 40bytes
Starting at (address/offset): Block number 1
The RFH5xx can read or write a maximum of 28bytes within a process datum. For
queries with large amounts of data, two queries must be sent. This procedure also
applies to the other modes (Write, Auto-Read, Auto-Write).
