Abstract: A digital interface circuit includes a queue block configured to be coupled between an analog-to-digital converter (ADC) and a Direct Memory Access (DMA) controller of a processor, where the queue block comprises a command buffer and is configured to: receive a first command from the DMA controller; store the first command in the command buffer; modify the first command in accordance with first control bits of the first command to generate a modified first command; and send the modified first command to the ADC.

Abstract: An electronic device includes a power management circuit generating output for a plurality of voltage monitors that each detect whether voltages received from a test apparatus are at least a different minimum threshold. The power management circuit also generates a test enable signal indicative of whether the test apparatus is supplying the minimum required voltages to the electronic device. A control circuit receives the output for the plurality of voltage monitors and the test enable signal and generates at least one control signal as a function of the output for the plurality of voltage monitors and the test enable signal. An output circuit receives the at least one control signal and generates an interface control signal that selectively enables or disables interface with analog intellectual property packages within the electronic device, in response to the at least one control signal.
