The External Memory Interface (EMIF) provides a memory extension to asynchronous memories or other
slave devices.
Several interfaces are implemented to enhance the debugging capabilities of application code. In addition
to the built in ARM Cortex™-R4F CoreSight™ debug features, an External Trace Macrocell (ETM)
provides instruction and data trace of program execution. For instrumentation purposes, a RAM Trace Port
Module (RTP) is implemented to support high-speed output of RAM accesses by the CPU or any other
master. A Direct Memory Module (DMM) gives the ability to write external data into the device memory.
Both the RTP and DMM have no or only minimum impact on the program execution time of the application
code. A Parameter Overlay Module (POM) can re-route Flash accesses to the EMIF, thus avoiding the
re-programming steps necessary for parameter updates in Flash.
