Local Memory

The SRAM module has the following features:
4.3.1
The SRAM module provides a general-purpose memory block the ColdFire core can access in a single
cycle. The location of the memory block can be set to any 4-Kbyte address boundary within the 4-Gbyte
address space. The memory is ideal for storing critical code or data structures or for use as the system stack.
Because the SRAM module is physically connected to the processor's high-speed local bus, it can quickly
service core-initiated accesses or memory-referencing commands from the debug module.
Section 4.1, “Interactions Between Local Memory
hits multiple local memory resources.
4.3.2
The MCF5272 implements the SRAM base address register (RAMBAR), shown in
described in the following section.

Addresses not assigned to the register and undefined register bits are reserved. Write accesses to
these bits have no effect; read accesses return zeros.
The reset value column indicates the register initial value at reset. Uninitialized fields may contain
random values after reset.
