Example: in
Write command
The Write button launches RF requests to write data to the M24LR64-R EEPROM from the
block address specified in the from field to the block address entered in the to field.
In
Figure 39. Initiating a write operation
You can choose to write the same byte four times by changing the value in the Fill with field.
In the example below, the byte 55 is to be written four times.

Get Multiple Block Security Status command
The Get Multiple Block Security Status button launches RF requests to read the security
statuses of the blocks that correspond to the address range specified in the from and to
fields.
Figure 41. Get Multiple Block Security Status button
Addresses are managed in the same way as for read operations. In
status byte is shown for the blocks with addresses ranging between 0x00E0 and 0x00FF
(sector 07).

49 (49h Hex) is the first piece of data read in block number 0002 (sector 0)
46 (46h Hex) is the second piece of data read in block number 0002 (sector 0)
00 (00h Hex) is the third piece of data read in block number 0002 (sector 0)
01 (01h Hex) is the fourth piece of data read in block number 0002 (sector 0)
39, the Write command fills the blocks 0000h to 001Fh with “A1 34 09 67”.
