| * is active and ready for use with a Power Amplifier (PA) or a Low Noise Amplifier (LNA), or both. |
| * |
| * Pins can be toggled by using two PPI channels and a GPIOTE channel. The hardware channel IDs are provided |
| * by the application and are to be regarded as reserved for as long as there is no PA/LNA toggling enabled. |
| * |
| * @note Avoid changing this configuration while the radio is in use, as this can lead to undefined consequences. |
