| This enables counter device support through the Generic Counter |
| interface. You only need to enable this, if you also want to enable |
| one or more of the counter device drivers below. |

| Say yes here to build support for the ACCES 104-QUAD-8 quadrature |
| encoder counter/interface device family (104-QUAD-8, 104-QUAD-4). |
| |
| A counter's respective error flag may be cleared by performing a write |
| operation on the respective count value attribute. Although the |
| 104-QUAD-8 counters have a 25-bit range, only the lower 24 bits may be |
| set, either directly or via the counter's preset attribute. Interrupts |
| are not supported by this driver. |
| |
| The base port addresses for the devices may be configured via the base |
| array module parameter. |
