System and method for scheduling access to an analog-to-digital converter and a microprocessor

A method of scheduling use of an analog-to-digital converter, the method comprising:

• copying a plurality of bits from a schedule register having a plurality of schedule bits to a request register having a plurality of request bits, wherein each of the plurality of schedule bits corresponds to a channel of an analog-to-digital converter;
• monitoring the plurality of request bits;
• determining whether at least one of the plurality of request bits is set;
• and
• blocking further copying to the request register after determining that at least one of the plurality of request bits is set.

A method of performing an analog-to-digital conversion, comprising:

• receiving a request to schedule an analog-to-digital conversion for a channel of a plurality of channels;
• scheduling an analog-to-digital conversion in response to receiving the request;
• performing the analog-to-digital conversion based on the request;
• and
• wherein data that indicates the request to schedule is stored in a programmable control register.
