The device also has an external clock prescaler (ECP) module that when enabled, outputs a continuous
external clock on the ECLK pin/ball. The ECLK frequency is a user-programmable ratio of the peripheral
interface clock (VCLK) frequency. This low frequency output can be monitored externally as an indicator of
the device operating frequency.
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
TMS570LSxxx5 is an ideal solution for high performance real time control applications with safety critical
requirements.
