pub type LCKK_R = BitReaderRaw<LCKK_A>;Expand description
Field LCKK reader - 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. Any error in the lock sequence aborts the lock. After the first lock sequence on any bit of the port, any read access on the LCKK bit will return 1 until the next MCU reset or peripheral reset.
