EXAMPLE
Example of Multiplying Encoder Mode X1
X1 Multiplying Encoder Mode
Quadrature input signals are used to count on the leading (up
direction) OR trailing (down direction) edge of A for a bidirectional
count, and channel B is used to determine the direction.
[ B = leads A, Count = Down; B = follows A, Count = Up ]
X2 Multiplying Encoder Mode
Quadrature input signals are used to count on leading AND trailing
edges of A for a bidirectional count, and channel B is used to
determine the direction.
[ B = leads A, Count = Down; B = follows A, Count = Up ]
X4 Multiplying Encoder Mode
Quadrature input signals are used to count on leading AND trailing
edges of A AND B for a bidirectional count, and channel B is used to
determine the direction.
[ B = leads A, Count = Down; B = follows A, Count = Up ]
