Some position encoders provide direction and clock outputs, instead of quadrature outputs. In such cases, direction-count mode can be used. The QEPA input provides the clock for the position counter and the QEPB input has the direction information. The position counter is incremented on every rising edge of a QEPA input when the direction input is high, and decremented when the direction input is low.
