Option byte description (continued)
TMU_KEY 5 [7:0]: Temporary unprotection key 4
TMU_KEY 6 [7:0]: Temporary unprotection key 5
TMU_KEY 7 [7:0]: Temporary unprotection key 6
TMU_KEY 8 [7:0]: Temporary unprotection key 7
TMU_MAXATT [7:0]: TMU access failure counter
BL[7:0]: Bootloader enable
Temporary unprotection key: Must be different from 0x00 or 0xFF
Temporary unprotection key: Must be different from 0x00 or 0xFF
Temporary unprotection key: Must be different from 0x00 or 0xFF
Temporary unprotection key: Must be different from 0x00 or 0xFF
TMU_MAXATT can be initialized with the desired value only if TMU is
disabled (TMU[3:0]=0101 in OPT6 option byte).
When TMU is enabled, any attempt to temporary remove the readout
protection by using wrong key values increments the counter.
When the option byte value reaches 0x08, the Flash memory and data
EEPROM are erased.
If this option byte is set to 0x55 (complementary value 0xAA) the
bootloader program is activated also in case of a programmed code
memory (for more details, see the bootloader user manual, UM0560).
