Interpreting Configuration Table Entry tuples

[llandre]

Hi all,

I need some help to interpret Configuration Table Entry tuples. I hope 
this is not a FAQ ...
I have a SanDisk ConnectPlus WiFi Card with 128 MB memory. I read the 
CIS with dump_cis (see the dump below). As you can see there are several 
Configuration Table Entry tuples (0x1b). I need to understand exactly 
how the card must be powered but some tuples say Vcc=5V, other ones say 
Vcc=3.3V. Which is the right one?

Thanks a lot in advance.
