5.3.6.4 Register Write Protection

To prevent any single software error from corrupting LVDSC behavior, certain registers in the address space can be write-protected by setting the bit WPEN in the LVDSC Write Protection Status Register (LVDSC_WPMR).

The following registers are write-protected when LVDSC_WPMR.WPEN is set:

• LVDSC Control Register
• LVDSC Configuration Register
• LVDSC User Control Bits Register

To enhance safety, the write protection can be locked until the next system reset by configuring LCKWPEN=1 (WPEN must be 1 in the same access). When LCKWPEN=1, any further write access to the WPEN bit has no effect. If LCKWPEN=1 and WPEN=0, the lock is not activated.
