Abstract
An electronic device includes at least two electronic components. A reset circuit includes: a parity control circuit; at least two first flip-flops, wherein each first flip-flop has an output coupled to at least one of the at least two electronic components; and at least two second flip-flops, wherein each second flip-flop has at least one output coupled to an input of the parity control circuit.
Claims21
A circuit for resetting an electronic device that comprises at least two electronic components, said circuit for resetting comprising:
- a parity control circuit;
- at least two first flip-flops, each first flip-flop comprising an output coupled to at least one of said at least two electronic components;
- and
- at least two second flip-flops, each second flip-flop comprising at least one output coupled to an input of said parity control circuit.
The method according to claim 12, further comprising, in response to said parity control circuit signaling the anomaly, requesting by said control circuit a resetting of said device.
A circuit, comprising:
- a plurality of electronic components;
- wherein each electronic component has a reset input;
- a plurality of first flip-flops coupled to a reset line;
- wherein each first flip-flop has an output coupled to the reset input of a corresponding electronic component;
- a plurality of second flip-flops coupled to the reset line;
- a first logic circuit configured to logically combine signals output from the plurality of second flip-flops;
- a second logic circuit configured to logically combine a signal output from the first logic circuit and a reset signal, wherein an output signal from the second logic circuit is applied to the reset line.
