sequencing /"time" flow in simulation/debug
I want to study the timing on acivities in the simulator/simulation /debug. So I had expected one could step by clock cycle and then (have a) log the output on e.g. two pins (GPIO...

UART prog. working on m8 not on m88
Hello; I have ported a small program essentially only doing UART TX/RX with the PC. After having substituted the change of symbols (UDR > UDR0, etc) the program compiles and...
