Application Report

SPNA163–September 2012

Initialization of the TMS570LS043x, TMS570LS033x and

RM42L432 Hercules ARM Cortex-R4 Microcontrollers

Charles Davenport............................................................................................................................

ABSTRACT

This application report provides a brief overview and initialization procedure of the TMS570LS043x,

TMS570LS033x, and RM42L432 series of microcontrollers in the Hercules™ family. "Hercules MCU" will

be used henceforth in this document to refer to any part in these series of microcontrollers.

The document also shows code fragments from source files that are generated using the HALCoGen tool.

All code constructs used in this document are defined in header files also generated by the same utility.

Nearly all of the project collateral and source code discussed in this application report can be generated

using the HalCoGen tool v3.02.02 or higher.
