Dear experts,

I'd like to say sorry that this mail is related only to (CardBus)
PC Card instead of PCI. I will appreciate any your answer.

I designed the PC Card host chip but I couldn't find the load of 
the external PC Card's CVS (CardBus Voltage Sense) pin when floated. 
According to the PC Card standard, CardBus 3.3V only PC Card, CVS1 should 
be connected to CCD1# and CVS2 should be open (floated). In this case,
I want to know the 'Cload' (capacitive load) of the floated CVS2 of PC Card.

I couldn't find any specifications in the PC Card standard documents.
I have measured 'Cload' of some CardBus PC Cards, but their results are
somewhat different. Please, let me know the maximum value of Cload.

Regards,
