Test logic method for an integrated circuit device

A digital logic controller including a first delay cell connectable to a signal input and operable to generate a first time delayed input signal, a second delay cell connectable to the signal input and operable to generate a second time delayed input signal, a counter connectable to the signal input via the first delay cell, two logic units to generate reset signal by one of logic units and to generate set signal by the other of logic units, and connected between the set of delay cells and a flip-flop operable to generate a counter valid signal at a flip-flop output, a first comparator connected to an output of the counter and operable to compare a counter output signal with a first target, a first logic gate connected to the flip-flop output, connected to the first comparator and operable to temporally deactivate processing of the counter output signal.

Digital logic controller

The motor driver of an horological motor consumes an important part of the electrical energy of the electronic circuit due to the fact that configuration data has to be transferred to configuration registers before each turn/step. In order to reduce the power consumption a circuitry is proposed, which detects a change in at least one of the configuration registers. This detection is used to trigger a refresh of the configuration registers only when actually a change in at least one of these configuration registers occurs.

Motor driver device with a horological motor driver and an associated configuration circuit

The present invention concerns an electronic circuit comprising a control signal processing circuit with a control signal input and a control signal output circuit, the processing circuit being arranged to process a control signal applied to the control signal input, and to operate in at least one of a first power mode and a second power mode, the second power mode having a lower power consumption than the first power mode. The electronic circuit further comprises a control signal processing circuit bypass means for providing, when the processing circuit is in the second power mode, a bypass connection for conveying the control signal from the control signal input to the control signal output circuit, thereby bypassing the processing circuit.
