Lpc2000

From the LPC2148 documentation it is not clear how the P0.31 pin
should be used for CONNECT feature.
Particularly, in the schematic p.32 of datasheet the pin is connected
to GND trough the relay winding, thus disabling the JTAG port, see 
p.10 of the datasheet.
Is there a schematic of a working connection of pin P0.31?
