Disconnecting

Use the standard Serial Wire Debug (SWD) Arm® CoreSight™ Debug Access Port (DAP) protocol to exit the debug interface mode.

This is handled using the built-in CxxxPWRUPREQ and CxxxPWRUPACK features found in the Arm CoreSight DAP. When the debugger stops requesting the debug domain or the complete system to be powered up, the device exits the debug interface mode.

We recommend a hard reset of the device after programming by doing a pin reset or a power cycle.
