3.26.1
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.
3.26.2
Embedded trace macrocell™
The ARM embedded trace macrocell provides a greater visibility of the instruction and data
flow inside the CPU core by streaming compressed data at a very high rate from the
