Nothing is assigned.
In an attempt to write to this bits, write “0”. The value, if read, turns
out to be indeterminate.

Note 1: Set bit 1 of the protect register (address 000A16) to “1” when writing new
values to this register.
Note 2: After setting this bit to "1", can not change to "0" by software.
