SpletSWD and JTAG selection mechanism SWJ-DP enables either an SWD or JTAG protocol to be used on the debug port. To do this, it implements a watcher circuit that detects a specific 16-bit selection sequence on the SWDIOTMS pin: A 16-bit sequence is used to switch from JTAG to SWD operation Another 16-bit sequence is used to switch from SWD to JTAG. SpletThe SWD interface is a two-pin (SWDIO/SWCLK) electrical alternative to the JTAG interface that has the same JTAG protocol on top. The SWD interface can be used to program the firmware of a processor and access its registers for debugging purposes. This interface and its associated protocol are now available in nearly all ARM® Cortex®-A ...

SpletSwitching between JTAG and SWD modes of debug. Some Cortex-M based MCUs support both SWD and JTAG, others support only SWD (such as NXP LPC11xx and LPC13xx). Where both are supported, there are special sequences defined to switch from JTAG mode (default) to SWD mode (and vice versa) that can sent to the core. SpletThe Arm SWD interface is a subset of the JTAG interface, making use of the TCK and TMS pins, which means that when connecting to an SWD device, the 10-pin JTAG connector can technically be used. The Arm JTAG and AVR JTAG connectors are, however, not pin-compatible, so this depends upon the layout of the target board in use. ...
