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 PHA only.

1: Edges are detected on both PHA and PHB.

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 (DISABLED): the detection and auto-correction function is disabled.

1 (ENABLED): the detection and auto-correction function is enabled.

1.. 63: Defines the filtering capabilities.

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