| * Configure a RTCIO pin based on encoded pin attributes. |
| * |
| * Input Parameters: |
| * rtcio_num - RTCIO pin to be configured. |
| * attr - Attributes to be configured for the selected RTCIO pin. |
| * The following attributes are accepted: |
| * - Direction (OUTPUT or INPUT) |
| * - Pull (PULLUP, PULLDOWN or OPENDRAIN) |
| * - Function (if not provided, assume function RTCIO by |
| * default) |
| * - Drive strength (if not provided, assume DRIVE_2 by |
| * default) |
| * |
| * Returned Value: |
| * Zero (OK) on success, or -1 (ERROR) in case of failure. |
