Pin 35 is 1.8V core voltage
Pin 33 is 3.3V for Input & Output (IO)driver and a number of other things.
If the IO comes up before the core voltage then there is the possibility of seeing unwanted pulses on the output pins.
To prevent this the capacitor between Pin 33 and 35 will act as a speed up or voltage divider to help 1.8V track the 3.3V.
Update to EVM documentation is in work.
