+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.
