These bits are not used.
The Lock/Protect Entry Register is used to set the victim and base pointers of
the TLB.
The victim pointer identifies the TLB entry which is due for eviction by the table
walking logic. The MPU core can also set it to select a TLB entry for reading
or writing.
The base pointer specifies which entries in the TLB are protected against
eviction by the table walking logic.
Note:
The LOCK_REG can only be modified by the MPU core when the table
walking logic is disabled.
