SDIO functions?

[Maximus <john.maximus@gmail.com>]

Hi,
   Just going through the sdio specs and ossman's patch.


  What are these functions and thier numbers in CMD 53

  Does that mean an SDIO Card can support upto 8 different functions?.

  An sdio card can be used as a wlan and camera (if it supports 2
functions wlan and camera).

 Is it like that?. Because i have not come across a card which
supports more than one function.

 What does "function" mean - does that mean some kind of firmware
inside the card or some kind electronics.

 I dont understand.


Thanks and Regards,
Jo
