PC does not increment after executing NOP #171

Closed ogamespec closed 1 year ago

The HDL is now running an NOP stream, but the Addr bus value is not increasing, and hence neither is the PC. We need to localize the problem and fix it.

Among other bugs..

adl/adh captured 0 somehow.

Although the first increment 0 -> 1 was successful.

It looks like T4 / T5 are mixed up.
