2.37 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
STM32F722xx and STM32F723xx 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
the USB or any other high-speed channel. The real-time instruction and data flow activity
can be recorded and then formatted for display on the host computer that runs the debugger
software. The TPA hardware is commercially available from common development tool
vendors.
The Embedded Trace Macrocell operates with third party debugger software tools.
