> The debug logic can be permanently locked, if the FAPR bit in the SECS register is cleared to 0. By default, the FAPR value
is 1 which means that the debugger can be locked and unlocked with the OCDDIS bit and Unlock ID in the option-setting
memory. Once the FAPR bit is cleared, the OCDDIS bit and Unlock ID cannot be changed, even if an ALeRASE command
is performed, and debugging through cJTAG interface is disabled permanently.
