Hello everybody,
I ordered a MuP21 Development Kit from Offete and while waiting for it
to arrive I take the chance to understand Chuck's MuP21-Code from
More on Forth Engines Vol 18.
What currently is unclear to me, is how the bit interleaving really works
and how it works in conjunction with the complementary polarity scheme.
Where are bits interleaved and toggled. In data? In adresses?
What about branch targets.
I would very much appreciate an up to date explanation...
Greetings,
Ulrich
