The PORT design has two registers for controlling pin direction, one to enable/disable output drivers (DIR) and one to enable input drivers (INEN) to be able to read the pin state from the gpio data register. If I recall the bare metal reference code toggled both but we can review if setting INEN for all pins and leaving it is acceptable as well to simplify things.
