| 12 | Say yes here to build support for the ACCES 104-QUAD-8 quadrature |
| 13 | encoder counter/interface device family (104-QUAD-8, 104-QUAD-4). |
| 14 | |
| 15 | Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and |
| 16 | also clears the counter's respective error flag. Although the counters |
| 17 | have a 25-bit range, only the lower 24 bits may be set, either directly |
| 18 | or via a counter's preset attribute. Interrupts are not supported by |
| 19 | this driver. |
| 20 | |
| 21 | The base port addresses for the devices may be configured via the base |
| 22 | array module parameter. |
