Description
Reset position counter. When set = 1, resets the position counter to
all zeros. Autoclears when the position counter is cleared.
Reset position counter on index. When set = 1, resets the position
counter to all zeros when an index pulse occurs. Autoclears when
the position counter is cleared.
Reset velocity. When set = 1, resets the velocity counter to all zeros
and reloads the velocity timer. Autoclears when the velocity counter
is cleared.
Reset index counter. When set = 1, resets the index counter to all
zeros. Autoclears when the index counter is cleared.

Description
Direction invert. When = 1, complements the DIR bit.
Signal Mode. When = 0, PhA and PhB function as quadrature
encoder inputs. When = 1, PhA functions as the direction signal
and PhB functions as the clock signal.
When = 1, BOTH PhA and PhB edges are counted (4X),
increasing resolution but decreasing range.
Invert Index. When set, inverts the sense of the index input.
Continuously reset position counter on index. When set = 1,
resets the position counter to all zeros when an index pulse
occurs at the next position increase (recalibration). Auto-clears
when the position counter is cleared.
Reserved
Index gating configuration:
when INXGATE(19)=1, pass the index when Pha=0 and Phb=0,
else block.
when INXGATE(18)=1, pass the index when Pha=0 and Phb=1,
else block.
when INXGATE(17)=1, pass the index when Pha=1 and Phb=1,
else block.
when INXGATE(16)=1, pass the index when Pha=1 and Phb=0,
else block.
