SWDJTAG
SWDJTAG is a debugging and programming interface primarily used with STMicroelectronics microcontrollers. It stands for Serial Wire Debug (SWD) and Joint Test Action Group (JTAG). SWDJTAG allows developers to interact with a microcontroller for tasks such as debugging code, flashing firmware, and reading/writing memory. It provides a way to control the microcontroller's execution, inspect its internal state, and load new programs onto it.
The SWD interface is a two-wire protocol, typically consisting of a Serial Wire Debug Data (SWDIO) pin
