If QUADMODE = 0, then the phase A and phase B encoding mode (see the following
figure) is enabled. In this mode, the relationship between phase A and B signals indicates
the counting direction, and phase A and B signals define the counting rate (FTM counter
is updated when there is an edge either at the phase A or phase B signals).
If PHAPOL = 0 and PHBPOL = 0, then the FTM counter increment happens when:
and the FTM counter decrement happens when:
