• POSEN: POSition ENabled
0 = disable position.
1 = enables the position measure on channel 0 and 1
• SPEEDEN: SPEED ENabled
0 = disabled.
1 = enables the speed measure on channel 0, the time base being provided by channel 2.
• QDTRANS: Quadrature Decoding TRANSparent
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.
• EDGPHA: EDGe on PHA count mode
0 = edges are detected on both PHA and PHB.
1 = edges are detected on PHA only.
• INVA: INVerted phA
0 = PHA (TIOA0) is directly driving quadrature decoder logic.
1 = PHA is inverted before driving quadrature decoder logic.
• INVB: INVerted phB
0 = PHB (TIOB0) is directly driving quadrature decoder logic.
1 = PHB is inverted before driving quadrature decoder logic.
• SWAP: SWAP PHA and PHB
0 = no swap between PHA and PHB.
1 = swap PHA and PHB internally, prior to driving quadrature decoder logic.
• INVIDX: INVerted InDeX
0 = IDX (TIOA1) is directly driving quadrature logic.
1 = IDX is inverted before driving quadrature logic.
• IDXPHB: InDeX pin is PHB pin
0 = IDX pin of the rotary sensor must drive TIOA1.
1 = IDX pin of the rotary sensor must drive TIOB0.
• FILTER:
0 = IDX,PHA, PHB input pins are not filtered.
1 = IDX,PHA, PHB input pins are filtered using MAXFILT value.
• MAXFILT: MAXimum FILTer
1.. 63: defines the filtering capabilities
Pulses with a period shorter than MAXFILT+1 MCK clock cycles are discarded.
