10 * The whole nRF pin configuration information is encoded in a 32-bit bitfield
11 * organized as follows:
12 *
13 * - 31..18: Pin function.
14 * - 17: Clockpin enable.
15 * - 16: Pin inversion mode.
16 * - 15: Pin low power mode.
17 * - 14..11: Pin output drive configuration.
18 * - 10..9: Pin pull configuration.
19 * - 8..0: Pin number (combination of port and pin).
