Было описано в мануале. Вот:
Remark: GPIO pins P0.29 and P0.30 are shared with the USB D+/− pins and must have the same direction. If either P0DIR bits 29 or 30 are configured LOW in the IO0DIR or FIO0DIR registers, both, P0.29 and P0.30, are inputs. If both, P0DIR bit 29 and bit 30 are HIGH, both, P0.29 and P0.30, are outputs.
