MOTOROLA
The following example shows how to set the MBAR to location 0x1000_0000 using the D0
register. Setting MBAR[V] validates the MBAR location. This example assumes all
accesses are valid:
move.1 #0x10000001,DO
movec DO,MBAR
6.2.3 System Configuration Register (SCR)
The system configuration register (SCR), Figure 6-3, provides information and control for
a variety of system features.
Table 6-3 describes SCR fields.
