6.2 Programming Model
The following sections describe the registers incorporated into the SIM.
6.2.1 SIM Register Memory Map
Table 6-1 shows the memory map for the SIM registers. The internal registers in the SIM
are memory-mapped registers offset from the MBAR address pointer defined in
MBAR[BA]. This supervisor-level register is described in Section 6.2.2, “Module Base
Address Register (MBAR).” Because SIM registers depend on the base address defined in
MBAR[BA], MBAR must be programmed before SIM registers can be accessed.

Although external masters cannot access the MCF5407’s
on-chip memories or MBAR, they can access any of the SIM
memory map and peripheral registers, such as those belonging
to the interrupt controller, chip-select module, UARTs, timers,
DMA, and I
