The only way CENSOR[0:1] can be changed is by setting or clearing the FLASH NVM fuses. In the
information censorship state, CENSOR[0:1] must be cleared to the cleared censorship state before
CENSOR[0:1] can be put into the no censorship state. While clearing CENSOR[0:1] the entire UC3F array
is erased. Thus the information stored in the UC3F array is made invalid while clearing CENSOR[0:1].
21.3.11.1 Setting and Clearing Censor
The value of each bit in CENSOR[0:1] is determined by the state of an NVM CAM cell. The NVM CAM
cell is not writable but instead may be set or cleared. Reading CENSOR[0:1] while setting or clearing with
the high voltage applied (CSC = 1 and EHV = 1) will return 0’s.
