Internal weak-pull up resistance value

How much is the resistance value of internal weak-pull up in LPC802 GPIO?

 

I'd like to keep a line which is connected to a MCU (LPC802) low level during it is in reset state. I believe that GPIO is configured as input function with internal weak-pull up resistance when the MCU is in reset state. Hear "reset state" means that the MCU's reset pin is low. Therefore, I consider placing an external pull-down resistance on the line and I'd like to know the resistance value of internal weak-pull up to calculate the appropriate external pull-down resistance value.
