STM32F398VE

Functional overview

3.27

Development support

3.27.1

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.

3.27.2

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

STM32F398VE through a small number of ETM pins to an external hardware trace port

analyzer (TPA) device. The TPA is connected to a host computer using a high-speed

channel. Real-time instruction and data flow activity can be recorded and then formatted for

display on the host computer running debugger software. TPA hardware is commercially

available from common development tool vendors. It operates with third party debugger

software tools.
