Serial Wire Debug

Summary
Serial Wire Debug, also known as SWD, is a electrical interface that is able to debug processors in a device. In iDevices, the connections that allow this debugging is only available when the SoC has a CPFM which is lower than 0x01, or if the device is demoted. This page lists the SWD probes that can interact with the connections and therefore debug the device, if they meet one of the previous conditions.
