Analog to digital converter with configurable sequence controller

A method of operating an analog to digital converter (ADC) with input multiplexor circuitry having a plurality of analog input terminals for receiving a plurality of analog signals, comprising the steps of:

• 1) programming a first plurality of states with a respective selector value, where each selector value specifies any one of the plurality of analog input terminals;
• 2) programming a different second plurality of states with a respective selector value, where each selector value specifies any one of the plurality of analog input terminals;
• 3) receiving a plurality of analog signals on respective ones of the plurality of analog input terminals;
• 4) accessing each state of the first plurality of states in a sequential manner and selecting an analog input terminal specified by a selector value contained therein in response to a first trigger;
• 5) accessing each state of the second plurality of states in a sequential manner and selecting an analog input terminal specified by a selector value contained therein in response to a second trigger;
• and
• 6) performing an analog to digital conversion on selected ones of the plurality of analog signals in accordance with the selector value contained in each state.
