Documentation Error EMX User Manual?

In the Cobra schematics :
pin 7 IO 4 is connectect to EMX P2.5

But in the EMX User Manual PDF
this is 7 P2.30 IO4* UP Button General purpose digital I/O

I assume the User manual is wrong ?

Where is the error? IO4 is up button and general IO

On the FEZ Cobra 1.2 schematics IO4 = ( button up) = controller pin P2.5

In the EMX user manual (pdf) the IO4 = LPC2478 name P2.30

I think the first ( P2.5) is right.
