* added input buffers (LVC with Ioff feature) to prevent high current flow
from powered-up target into powered-down FT2232D inputs;

* added series resistors on outputs to limit current flow from powered-up
adapter into powered-down Calypso target;

* buffer IC changed from 74LVC125A to 74LVC541A.]]> Mychaela Falconia <falcon@freecalypso.org> Sun, 28 Jun 2020 22:06:24 +0000 duart28/src/primitives: adapted from fc-uja https://www.freecalypso.org/hg/fc-small-hw/log/43097651a26d/duart28/src/primitives Mychaela Falconia <falcon@freecalypso.org> Sat, 13 Jun 2020 05:28:01 +0000
