Special single chip erase and unsecure sequence:
Freescale Semiconductor
1. Reset into special single chip mode.
2. Write an appropriate value to the ECLKDIV register for correct timing.
3. Write 0xFF to the EPROT register to disable protection.
4. Write 0x30 to the ESTAT register to clear the PVIOL and ACCERR bits.
5. Write 0x0000 to the EDATA register (0x011A–0x011B).
6. Write 0x0000 to the EADDR register (0x0118–0x0119).
7. Write 0x41 (mass erase) to the ECMD register.
8. Write 0x80 to the ESTAT register to clear CBEIF.
9. Write an appropriate value to the FCLKDIV register for correct timing.
10. Write 0x00 to the FCNFG register to select Flash block 0.
11. Write 0x10 to the FTSTMOD register (0x0102) to set the WRALL bit, so the following writes
12. Write 0xFF to the FPROT register to disable protection.
13. Write 0x30 to the FSTAT register to clear the PVIOL and ACCERR bits.
14. Write 0x0000 to the FDATA register (0x010A–0x010B).
15. Write 0x0000 to the FADDR register (0x0108–0x0109).
