Hi All,

I am writing code for a resistive touch-screen and need to measure 
voltage on Digital Output Pins  P0.27, P0.28, P0.29 and P0.30 (as part 
of calibration process)

Has anyone successfully sampled those ports while they are configured 
as digital output. According to the user manual (table 143 pg 198) it 
can be done and is to be used to calibrate the A/D

I posted a message like this several weeks ago.  Philips said the
public was never supposed to see that it is possible, they would not
comment on how to do it and that it would be removed from the next
version of the manual.
