Unified System Interface Unit (USIU) Overview
The USIU supports the internal Flash censorship mechanism on the MPC561/MPC563 to protect the Flash
contents. Refer to
MPC561/MPC563 from the external world while the Flash is in censorship mode and in a censorship state.
The internal Flash array will be either locked or accessible only after the entire array contents have been
erased. The MPC561/MPC563 is in censored mode if one of the following events occurs:

The address shown for each register is relative to the base address of the MPC561/MPC563 internal
memory map. The internal memory block can reside in one of eight possible 4 Mbyte memory spaces. See
