QCAPEN: Position Counter Input Capture Enable bit
1 = Positive edge detect of home input triggers position capture function
0 = HOMEx input event (positive edge) does not trigger a capture event
FLTREN: QEAx/QEBx/INDXx/HOMEx Digital Filter Enable bit
1 = Input pin digital filter is enabled
0 = Input pin digital filter is disabled (bypassed)
QFDIV<2:0>: QEAx/QEBx/INDXx/HOMEx Digital Input Filter Clock Divide Select bits
111 = 1:256 clock divide
110 = 1:64 clock divide
101 = 1:32 clock divide
100 = 1:16 clock divide

010 = 1:4 clock divide
001 = 1:2 clock divide
000 = 1:1 clock divide
OUTFNC<1:0>: QEI Module Output Function Mode Select bits
11 = The CTNCMPx pin goes high when QEIxLEC  POSxCNT  QEIxGEC
10 = The CTNCMPx pin goes high when POSxCNT  QEIxLEC
01 = The CTNCMPx pin goes high when POSxCNT  QEIxGEC
00 = Output is disabled
SWPAB: Swap QEA and QEB Inputs bit
1 = QEAx and QEBx are swapped prior to quadrature decoder logic
0 = QEAx and QEBx are not swapped
HOMPOL: HOMEx Input Polarity Select bit
1 = Input is inverted
0 = Input is not inverted
IDXPOL: HOMEx Input Polarity Select bit
1 = Input is inverted
0 = Input is not inverted
QEBPOL: QEBx Input Polarity Select bit
1 = Input is inverted
0 = Input is not inverted
QEAPOL: QEAx Input Polarity Select bit
1 = Input is inverted
0 = Input is not inverted
HOME: Status of HOMEx Input Pin After Polarity Control bit
1 = Pin is at logic ‘1’
0 = Pin is at logic ‘0’
