   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.

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

  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.

  29           The base port addresses for the devices may be configured via the base
  30           array module parameter.
