摘要： An integrated circuit comprises means responsive to a normally changing signal at an input of the integrated circuit to implement a primary function of the circuit, and means for monitoring this normally changing signal at the input in question of the integrated circuit. This monitoring means is responsive to suspension of the normally changing signal to communicate a signal for implementation of a secondary function of the circuit. In an exemplary embodiment, the invention is directed towards implementation of power-down of the circuit, without using an explicit power-down or reset pin. An input signal which normally changes at minimum rate, e.g. preferably a clock signal, is held in a fixed state for a minimum duration to invoke the reset or power-down mode. An integrated circuit may thus be powered-down or reset where no explicit power-down or reset pin is available.

摘要： Automatic range shifting for an analog to digital converter (ADC) includes combining an external analog input and a DAC output to provide an input to the ADC, detecting whether the range of the output of the ADC is above a predetermined upper range limit or below a predetermined lower range limit, and generating an adjustment code to increase the DAC output if the ADC output is above the upper range limit and to decrease the DAC output if the ADC output is below the lower range limit for decreasing the ADC input when the ADC output is above the upper limit and to increase the ADC input when the ADC output is below the lower limit to keep the ADC input within the ADC range.
