| LCKK | Lock key This bit can be read any time. It can only be modified using the lock key write sequence. LOCK key write sequence: WR LCKR[16] = 1 + LCKR[15:0] WR LCKR[16] = 0 + LCKR[15:0] WR LCKR[16] = 1 + LCKR[15:0] RD LCKR RD LCKR[16] = 1 (this read operation is optional but it confirms that the lock is active) Note: During the LOCK key write sequence, the value of LCK[15:0] must not change. Note: Any error in the lock sequence aborts the lock. Note: After the first lock sequence on any bit of the port, any read access on the LCKK bit returns 1 until the next MCU reset or peripheral reset. 0 (B_0x0): Port configuration lock key not active 1 (B_0x1): Port configuration lock key active. The GPIOx_LCKR register is locked until the next MCU reset or peripheral reset. |
