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.
|
|
|
|
The base port addresses for the devices may be configured via the base
|
|
array module parameter. The interrupt line numbers for the devices may
|
|
be configured via the irq array module parameter.
