Programming Lock Bits
1. Programming Lock Bits
Programming Lock Bits to a lock mode equal or lower than the current causes one word of Flash to be cor-
rupted. The location of the corruption is random.
Problem Fix / Workaround
When programming Lock Bits, make sure lock mode is not set to present, or lower levels.

ESD HBM (ESD STM 5.1) level ±1000V
• Programming Lock Bits
1. ESD HBM (ESD STM 5.1) level ±1000V
The device meets ESD HBM (ESD STM 5.1) level ±1000V.
Problem Fix / Workaround
Always use proper ESD protection measures (Class 1C) when handling integrated circuits before and during
assembly.
2. Programming Lock Bits
Programming Lock Bits to a lock mode equal or lower than the current causes one word of Flash to be cor-
rupted. The location of the corruption is random.
Problem Fix / Workaround
When programming Lock Bits, make sure lock mode is not set to present, or lower levels.
