1.10.2 English

This input signal synchronously indicates if the dynamic phase shift is an increment or decrement operation (positive or negative phase shift). PSENCDEC is asserted High for increment and Low for decrement. There is no phase shift overflow associated with the dynamic phase shift operation. If 360° or more are shifted, the phase wraps around, starting at the original phase.
