Working with an LPCxpresso 1769 Rev B Board.  It doesn't appear that all pins shown on schematic to be connected to Expansion Connector are connected.  I've only worked through a few but for example, P0.22 is shown on LPCxpresso LPC1769 Rev B schematic to go to J6-24.  However, on the board they are not connected.  P0.22 *is* connected to LED2 via R34 as I am able to flash the LED using that port.  However, the signal does not appear on J6-24 and also there is no continuity between P0.22 and J6-24.  Am I interpreting the schematic correctly?

Thanks,
