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

19 Say yes here to build support for the ACCES 104-QUAD-8 quadrature
20 encoder counter/interface device family (104-QUAD-8, 104-QUAD-4).

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