ABSTRACT:
A method of scheduling use of an analog-to-digital converter is disclosed and includes writing to a schedule register that has a plurality of schedule bits. Each of the plurality of schedule bits corresponds to a channel of an analog-to-digital converter. Further, the method includes copying the plurality of bits from the schedule register to a request register that has a plurality of request bits. The method also includes monitoring the plurality of request bits and determining whether at least one of the plurality of request bits is set. Additionally, the method includes blocking further copying to the request register after determining that at least one of the plurality of request bits is set.
