Chapter 4
Local Memory
This chapter describes the MCF5272 implementation of the ColdFire Version 2 core local memory
specification. It consists of the following sections.
4.1
Depending on configuration information, instruction fetches and data read accesses may be sent
simultaneously to the SRAM, ROM, and cache controllers. This approach is required because the
controllers are memory-mapped devices and the hit/miss determination is made concurrently with the read
data access. Power dissipation can be minimized by configuring the ROM and SRAM base address
registers (ROMBAR and RAMBAR) to mask unused address spaces whenever possible.
If the access address is mapped into the region defined by the SRAM (and this region is not masked), it
provides the data back to the processor and any cache or ROM data is discarded. If the access address does
not hit the SRAM, but is mapped into the region defined by the ROM (and this region is not masked), the
ROM provides the data back to the processor and any cache data is discarded. Accesses from the SRAM
and ROM modules are never cached. The complete definition of the processor’s local bus priority scheme
for read references is as follows:
