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.
