19Description:
20		Configure the counter associated with Signal Y for
21		non-synchronous or synchronous load mode. Synchronous load mode
22		cannot be selected in non-quadrature (Pulse-Direction) clock
23		mode.
24
25		non-synchronous:
26			A logic low level is the active level at this index
27			input. The index function (as enabled via preset_enable)
28			is performed directly on the active level of the index
29			input.
30
31		synchronous:
32			Intended for interfacing with encoder Index output in
33			quadrature clock mode. The active level is configured
34			via index_polarity. The index function (as enabled via
35			preset_enable) is performed synchronously with the
36			quadrature clock on the active level of the index input.
