EEPROM area
The 9 blocks between addresses 7 and 15 are EEPROM blocks of 32 bits each (36 Bytes in
total). (See
READ_BLOCK and WRITE_BLOCK commands. The WRITE_BLOCK command for the
EEPROM area always includes an Auto-Erase cycle prior to the Write cycle.
Blocks 7 to 15 can be Write-protected. Write access is controlled by the 9 bits of the
OTP_Lock_Reg located at block address 255 (see
details). Once protected, these blocks (7 to 15) cannot be unprotected
