0 = Disable position.

1 = Enables the position measure on channel 0 and 1.

0 = Disabled.

1 = Enables the speed measure on channel 0, the time base being provided by channel 2.

0 = Full quadrature decoding logic is active (direction change detected).

1 = Quadrature decoding logic is inactive (direction change inactive) but input filtering and edge detection are performed.

0 = Edges are detected on both PHA and PHB.

1 = Edges are detected on PHA only.

0 = PHA (TIOA0) is directly driving quadrature decoder logic.

1 = PHA is inverted before driving quadrature decoder logic.

0 = PHB (TIOB0) is directly driving quadrature decoder logic.

1 = PHB is inverted before driving quadrature decoder logic.

0 = No swap between PHA and PHB.

1 = Swap PHA and PHB internally, prior to driving quadrature decoder logic.

0 = IDX (TIOA1) is directly driving quadrature logic.

1 = IDX is inverted before driving quadrature logic.

0 = IDX pin of the rotary sensor must drive TIOA1.

1 = IDX pin of the rotary sensor must drive TIOB0.

0 = IDX,PHA, PHB input pins are not filtered.

1 = IDX,PHA, PHB input pins are filtered using MAXFILT value.

1.. 63: Defines the filtering capabilities.

Pulses with a period shorter than MAXFILT+1 MCK clock cycles are discarded.
