ABSTRACT:
An analog-to-digital converter (ADC) system is disclosed and includes a programmable control register and a plurality of channels, each channel having an associated request bit within the programmable control register. The ADC system also includes a scheduler responsive to the programmable control register, the scheduler comprising logic to monitor a plurality of request bits to detect when any of the request bits are set. A method of scheduling analog-to-digital conversion is disclosed and includes receiving a request to schedule an analog-to-digital conversion for a channel of a plurality of channels. The method also includes scheduling an analog-to-digital conversion in response to receiving the request and performing the analog-to-digital conversion based on the request, where data that indicates the request is stored in a programmable control register.
