Serial wire JTAG debug port (SWJ-DP)
The ARM SWJ-DP Interface is embedded. and is a combined JTAG and serial wire debug
port that enables either a serial wire debug or a JTAG probe to be connected to the target.
The JTAG TMS and TCK pins are shared respectively with SWDIO and SWCLK and a
specific sequence on the TMS pin is used to switch between JTAG-DP and SW-DP.
