MOTOROLA
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.
