Asking more in hope than expectation really, but does anyone know if the STM32F20x (specifically, STM32F205RB) supports ETB? J-Link doesn't report it;

ETB is not present.
....and I don't see it in the datasheet either so I'm pretty sure I know the answer to my own question...but having gone to all of the trouble to include the ETM I'm sorta surprised there's no ETB there too....
