Re: Wakeup from a PCI device

Bruce,

Where is the Cardbus WAKEUP pin documented? I can't find it in the 
PC Card standard or the March '96 update to the standard (which 
included a complete updated list of the Cardbus pins). Could you
point me to a source for the documentation of that pin?

Thanks,
Frank
