Abstract
A digital output monitor circuit includes a first digital circuit that performs mutual conversion between serial data and parallel data, a second digital circuit that decodes data output from the first digital circuit and generates a control signal for an analog circuit, and a third digital circuit that converts at least the control signal for an analog circuit into digital data. The first digital circuit converts the data output from the third digital circuit into serial data and outputs as an output data signal.
Claims20
A digital output monitor circuit comprising:
- a first digital circuit configured to perform mutual conversion between serial data and parallel data;
- a second digital circuit configured to decode data output from the first digital circuit and to generate a control signal for an analog circuit;
- and
- a third digital circuit configured to output digital data,
- wherein at least the control signal is input to the third digital circuit, and
- wherein the first digital circuit is further configured to convert the digital data output from the third digital circuit into the serial data, and to output the serial data as an output data signal.
