MPC555
USER’S MANUAL
The default state is to allow dual-mapping data accesses only; this means that dual
mapping is possible only for data accesses on the internal bus. Also, the default state
takes the lower two Mbytes of the MPC555 / MPC556 internal flash memory. Hence,
caution should be taken to change the dual-mapping setup before the first data ac-
cess.

Dual mapping is not supported for an external master when the mem-
ory controller serves the access; In such a case, the MPC555 /
MPC556 terminates the cycle by asserting TEA.
