I²C READ commands
The Read button issues read commands to the M24LRxx connected to the I2C reader. To
do so, select the I2C READ area, and then press on the Read button.
Read command to the memory array
To read the memory array, select Memory from the list and specify the address range to be
read. Then click on the Read button. Addresses are managed in the same way as for RF
commands (see Section 3.2.7: Read command).
Figure 68 shows an example where the user decides to issue a Read Memory operation
from address 0010h to address 003Fh.
