Flutter
During quadrature mode, a disparity may occur between the number of neg-
ative edges of PC1 and PC0 or the number of positive edges of PC1 and
PC0. This could indicate flutter on one reed switch or one reed switch may
be faulty.
0: No flutter detected.
1: Flutter detected.
Direction
Only applicable for quadrature mode.
(First letter is PC1; second letter is PC0)
