D.3 System Integration Module
Table D-3 displays the SIM address map. The column labeled “Access” indicates the
privilege level at which the CPU must be operating to access the register. A designa-
tion of “S” indicates that supervisor access is required. A designation of “S/U” indicates
that the register can be programmed to the desired privilege level.
