CMSIS-DAP supports target Devices that contain one or more Cortex processors. A Device provides a Debug Access Port (DAP) typically either with a 5-pin JTAG or with a 2-pin Serial Wired Debug (SWD) interface that connects to a Debug Unit. CMSIS-DAP is the interface firmware for a Debug Unit that connects the Debug Port to USB. Debuggers that execute on a host computer connect via USB and the Debug Unit to the Device which runs the application software.</p> +<div class="image"> +<img src="CMSIS_DAP_INTERFACE.png" alt="CMSIS_DAP_INTERFACE.png"/> +<div class="caption"> +CMSIS-DAP Overview</div></div> + <h2>Benefits of CMSIS-DAP</h2> +<ul> +<li>Provides a standardized interface for debuggers.<ul> +<li>Interfaces to many standard debuggers is already available.
