1. ATE mode disable bit - Efuse byte 35 bit[7]

2. TAG enable bit on Boot ROM Exit - Efuse byte 34 bit[1] - Bit[4]

3. Authentication Bit for the ECDSA key generation - Efuse byte 483 bit[0]

4. Authentication key region - Efuse bytes 128 - 191

5. ECC private key region - Efuse byte 0 - 31

6. Custom User space region - Efuse byte 192 - 479

7. Custom TAG update region - Efuse bytes 508 - 509

Once you run the utility, you will see the GUI as shown in Figure 1-3: “CEC1702

Efuse Programming tool input form”. The user is required to fill in the following

information in the tool to generate the binary and hex file required to program the
