Capacitor sense button on MAX V CPLD Dev Board

Does any one know how is connected the capacitor sense button on the Altera MAX V CPLD Development Board?

Ex.: Push buttons PB0 and PB1 are well documented in the "MAX V CPLD Development Board Reference Manual" where it is said that PB0 drives the M9 pin and PB1 drives the R3 pin.

But noting is said about the capacitor sense button. I can't find the information no where. Neither can I find any schematic of the board. Very frustating!

Can anyone help?

    The schematic is included with the board design files. The "capacitor sense button" seems to connect to Pin C11 without any additional electronic.

    P.S.: There are also design examples supporting the "touch" button.
