3.26 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
STM32F373x 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 USB, Ethernet, or
any other 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.
