Functional overview

3.28

Development support

3.28.1

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.

Debug is performed using only two pins instead of the five required by the JTAG (JTAG pins

can then be reused as GPIOs with alternate function): the JTAG TMS and TCK pins are

shared with SWDIO and SWCLK, respectively, and a specific sequence on the TMS pin is

used to switch between JTAG-DP and SW-DP.

3.28.2

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

STM32WB55xx through a small number of ETM pins to an external hardware trace port

analyzer (TPA) device. Real-time instruction and data flow activity be recorded and then

formatted for display on the host computer that runs the debugger software. TPA hardware

is commercially available from common development tool vendors.

The Embedded Trace Macrocell operates with third party debugger software tools.
