Abstract
A shaft angle encoder interface for quadrature channel incremental shaft angle encoders utilizes a quadrature decoder/counter interface integrated circuit for providing a digital signal output representative of the angle. The digital signal output is provided by a high byte and low byte multiplexer. The integrated circuit includes inhibit logic for inhibiting updating the data when the output is read. A state machine controls latches that receive the high byte and low byte to assemble an output digital angle signal and provides control signals to the integrated circuit so that the inhibit mode is not activated.
