| 9 | This enables counter device support through the Generic Counter | |
| 10 | interface. You only need to enable this, if you also want to enable | |
| 11 | one or more of the counter device drivers below. | |

| 23 | A counter's respective error flag may be cleared by performing a write | |
| 24 | operation on the respective count value attribute. Although the | |
| 25 | 104-QUAD-8 counters have a 25-bit range, only the lower 24 bits may be | |
| 26 | set, either directly or via the counter's preset attribute. Interrupts | |
| 27 | are not supported by this driver. | |
| 28 | ||
| 29 | The base port addresses for the devices may be configured via the base | |
| 30 | array module parameter. | |
