25.6.8.2 Address Spaces

The SmartEEPROM address space is divided in two distinct areas:

• DATA
  • Starts at offset 0x0
  • Size is 512B, 1KB, 2KB, 4KB, 8KB, 16KB, 32KB, 64KB depending on SEESTAT.PSZ and SEESTAT.SBLK (refer to “SmartEEPROM virtual size”)
  • This area is write protected if SEESTAT.LOCK is set. SEESTAT.LOCK is non volatile.
  • Commands LSEE and USEE respectively lock and unlock the SmartEEPROM.
• REGISTER:
  • Starts at offset 0x10000
  • Size is 20B
  • This area is write protected if either
    • SEESTAT.LOCK is set (non-volatile)
    • SEESTAT.RLOCK is set (volatile).

Commands LSEER and USEER respectively lock and unlock the SmartEEPROM register address space.

As a consequence both SEESTAT.LOCK and SEESTAT.RLOCK must be low to write the SmartEEPROM register address space.
