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
STM32F10xxx 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 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.
