Hi I will interprit the pdf to it saying the little triangle low in will be for active low pins and use a ~ so it should be clear enough.
Yea I know how it is annoying when they want to have a standard but require silver or gold crossing a palm to get it like USB. Hopefuly when I make a PCI kicad board using a fpga it will not have USB. But I am set now and thanks for your help. --- In [email protected], Robert <birmingham_spi...@...> wrote: > > Thanks, that's certainly a useful document.
