Keil MDK is the most comprehensive software development solution for Arm-based microcontrollers and includes all
components that you need to create, build, and debug embedded applications.
MDK Version 5.28a introduces a free edition to program Holtek's Arm Cortex-M0+ based devices. It improves support
for devices that have a trace clock that is independent from the core clock and can save the output of System Analyzer in
a file for further processing.
Note: The 7-day MDK-Professional trial license does not work with MDK v5.26/v5.27/v5.28. If you require
a trial license, please contact your distributor or Arm sales.
