Hi,

I asked philips for the value of the pull ups.
They didn't tell me the value, they only said that they are very weak 
pull-ups.
It seems to be some kind of secret at philips...
We decided to use external pull ups to get no bad surprises in future.

Perhaps the value could be measured by enabling one, driving it low and 
measuring the current to the supply. Probably 100k or something like that.
