19.8.4 Setting and Clearing Censor
MPC555
USER’S MANUAL
CMF EEPROM Status
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.
The value of each bit in CENSOR[0:1] is determined by the state of two NVM bits in a
special NVM fuse as shown in
main flash array. The NVM fuse is not writable but instead may be set or cleared. The
two NVM bits in the NVM fuse are programmed and erased simultaneously to change
= Indicates that the CMF array can not be accessed.
