Holtek provides CMSIS-compliant device support which makes it easy to add CMSIS software components to your applications, such as Keil RTX or FreeRTOS kernels. Both are supported in the µVision Debugger with the Component Viewer for kernel awareness and the Event Recorder for analyzing the dynamic run-time behavior.
