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.
