According to page 76-77 of the user manual P0.2, P0.3, P0.11, P0.14 are
open drain outputs for i2c use.  These need pullups when used as output
because they will only pull low.  FYI, All P1 pins have internal (~50k?)
pullups if used as inputs.  P0 pins do not.  Jeff.

	The i2c pins must have external 10k pull ups added to work as
GPIO 
	correctly...this is not documented clearly at all!!
