Development support

3.42.1

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 two pins only instead of five required by the JTAG (JTAG pins can be reused as GPIO

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.

3.42.2

Embedded Trace Macrocell

The Arm Embedded Trace Macrocell (ETM) 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 devices 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 ETM operates with third party debugger software tools.
