ROMBAR can be configured similarly, as described in
Power
4.4
The ROM modules has the following features:
4.4.1
The ROM module contains tabular data that the ColdFire core can access in a single cycle. The ROM can
be located on any 16-Kbyte address boundary in the 4-Gbyte address space.
Between Local Memory
resources.
4.4.2
The MCF5272 implements the ROM base address register (ROMBAR), shown in
described in the following section.
4.4.2.1
ROMBAR determines the base address location of the internal ROM module, as well as the definition of
the allowable access types. ROMBAR can be accessed in supervisor mode using the MOVEC instruction
with an Rc value of 0xC00. It can also be read when the processor is in background debug mode (BDM).
To access the ROM module, ROMBAR should be initialized with the appropriate base address.
