JTAG Interface on ADSP-21479 EZ-BOARD

I am working with the JTAG Interface on the ADSP-21479 EZ-Board and I found a conflict with pin-out of the interface. Pin-1 of the interface (Block - P1 in the schematic of the EZ-Board manual) is shown to be connected to VDD (3.3 V) through a pull-up resistor, whereas it is supposed to be connected to GND. To verify this, I checked the EE-68 application note and the pin-1 needs to be connected to GND. So, can anyone tell me the reason behind connecting the Pin-1 to VDD in the schematic of the EZ-Board.
