B.3 ACCESS CONTROL UNITS
The information in this section replaces the information in Section 3 Memory Management
Unit (Except MC68EC040 and MC68EC040V) . When reading Section 4 Instruction and
Data Caches , disregard any references to the MMU; remember the functionality of the
access control registers has replaced that of transparent translation registers. The
MC68EC040 contains two independent ACUs, one for instructions and one for data. Each
ACU allows memory selections to be made requiring attributes particular to peripherals,
shared memory, or other special memory requirements. The following paragraphs describe
the ACUs and the access control registers contained in them.
