In ATZB-S1-256-3-0-C persistence memory is stored in the User Signature Data (Page 1) of Atmega256RFR2 SoC with

starting address 0x0100. User Signature Data is isolated from the main flash and will not be cleared by Chip erase

Command.

Special commands are available to erase and write data to user signature pages via the JTAG interface (see section on

"Programming via the JTAG Interface” in Atmega256RFR2 datasheet [1] for details). User signature rows can be read

from software in the same way as the device and JTAG identifiers (see section "Reading the Signature Row from

Software" of Atmega256RFR2 datasheet[1]).

Note: 1 The MAC address stored inside the MCU is a uniquely assigned ID for each ZigBit and owned by Atmel.

User of the ZigBit application can use this unique MAC ID to address the ZigBit in end-applications. The MAC ID

can be read from the ZigBit using the Performance Analyzer Application that can be downloaded from
