Sorry, Leonid!

I was not enough accurate reading your RT specific question, and would be
interested to get any answer for the question too.
There is "In-Circuit Simulation" option on my Ceibo DS-51 ICE, that simulates
a program, but affects the ports and HW registers of the uCU.
However, I could not observe the program in "Emulation" mode while RTX51_tny
used.

Best regards,
Oleg T.
