Hi, 
 It's stated in the product specification, chapter 8.23.
For a normal GPIO configured as output, the max sink/source is 0.5 mA. 
 When you have configured your GPIO with high-drive, you can sink (or source) in total 15 mA (3 x 5 mA, 5 x 3 mA, etc) on all GPIOs that has this high-drive configuration. 
 Best regards
Håkon
