The Direct Memory Access Controller (DMA) has 16 channels, 32 control packets and parity protection on

its memory. A Memory Protection Unit (MPU) is built into the DMA to protect memory against erroneous

transfers.

The Error Signaling Module (ESM) monitors all device errors and determines whether an interrupt or

external Error pin/ball is triggered when a fault is detected. The nERROR can be monitored externally as

an indicator of a fault condition in the microcontroller.

The External Memory Interface (EMIF) provides a memory extension to asynchronous and synchronous

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 tracing of RAM and peripheral accesses by the CPU

or any other master. A Data Modification 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 internal

memory or to the EMIF, thus avoiding the re-programming steps necessary for parameter updates in

Flash.

With integrated safety features and a wide choice of communication and control peripherals, the

RM48Lx30 is an ideal solution for high performance real time control applications with safety critical

requirements.
