| 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. |
