What: /sys/bus/counter/devices/counterX/signalY/index_polarity
KernelVersion: 5.2
Contact: linux-iio@vger.kernel.org
Description:
Active level of index input Signal Y; irrelevant in
non-synchronous load mode.
What: /sys/bus/counter/devices/counterX/signalY/index_polarity_available
What: /sys/bus/counter/devices/counterX/signalY/synchronous_mode_available
KernelVersion: 5.2
Contact: linux-iio@vger.kernel.org
Description:
Discrete set of available values for the respective Signal Y
configuration are listed in this file.
What: /sys/bus/counter/devices/counterX/signalY/synchronous_mode
KernelVersion: 5.2
Contact: linux-iio@vger.kernel.org
Description:
Configure the counter associated with Signal Y for
non-synchronous or synchronous load mode. Synchronous load mode
cannot be selected in non-quadrature (Pulse-Direction) clock
mode.
non-synchronous:
A logic low level is the active level at this index
input. The index function (as enabled via preset_enable)
is performed directly on the active level of the index
input.
synchronous:
Intended for interfacing with encoder Index output in
quadrature clock mode. The active level is configured
via index_polarity. The index function (as enabled via
preset_enable) is performed synchronously with the
quadrature clock on the active level of the index input.
