Reading the memory array

Figure 69.

Result of a Read operation to the memory array

Figure 69 illustrates the result of the Read operation to the memory array. The first column

shows which sector is read. The second column indicates the address of the first byte in the

page. Then the third column gives the data.

Let us take the example corresponding to the data < 69 87 04 00 >

69 (69h Hex) is data for address 0028h (sector 0)

87 (87h Hex) is data for address 0029h (sector 0)

04 (04h Hex) is data for address 002Ah (sector 0)

00 (00h Hex) is data for address 002Bh (sector 0)

Reading the sector security status

To read all the sector security status bytes (RF block security), select Sector Security

Status (system) then press the Read button.

Figure 70 shows how to launch an operation to read the sector security status.
