LPC914 P1.2 configuration issue

Hi All,
I am having trouble getting my head around the P1.2 mode configuration on the Philips LPC914 device.

At reset the mode register bits read both high which according to the datasheet indicates that the P1.2 bit is in open-drain mode.

However I cannot write to this port bit.

I am missing something - anyone got any ideas?

Phoebe
