ANALOG-TO-DIGITAL CONVERTER CONTROLLERS INCLUDING CONFIGURABLE CONTEXTS
First Claim
1. A method of configuring a number of contexts for an analog-to-digital converter (ADC) controller, comprising:
- receiving a selection of a first context of a number of contexts, each context of the number of contexts including a number of registers;
receiving at least one parameter for the first context;
configuring the first context with the at least one parameter for the first context;
storing the first context as a first configured context of the ADC controller;
receiving a selection of at least one additional context of the number of contexts;
receiving at least one parameter for the at least one additional context;
configuring the at least one additional context with the at least one parameter for the at least one additional context; and
storing the at least one additional context as at least one additional configured context of the ADC controller.

Abstract
Various embodiments relate to analog-to-digital converter (ADC) controllers. An ADC controller may include a number of contexts configured for coupling to an ADC, wherein each context having at least one register for storing at least one configurable parameter. The ADC controller may also include a sequencer operatively coupled to the number of contexts and configured to perform a programmed conversion sequence based on one or more configurable parameters of one or more contexts of the number of contexts. Methods of performing an analog-to-digital (A/D) conversion sequence, and methods of configuring a number of contexts for an analog-to-digital converter (ADC) controller, are also disclosed.

7. An analog-to-digital converter (ADC) controller, the ADC controller comprising:
-
a number of contexts configured for coupling to an ADC, each context having at least one register for storing at least one configurable parameter; and a sequencer operatively coupled to the number of contexts and configured to perform a programmed conversion sequence based on one or more configurable parameters of one or more contexts of the number of contexts. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A method of performing an analog-to-digital (A/D) conversion sequence, the method comprising:
-
determining if a continuous operation bit of a first context of a number of contexts is asserted; determining if a sequence enable bit of the first context is asserted; in response to determining that the continuous operation bit of the first context is not asserted and the sequence enable bit of the first context is asserted, selecting a second context of the number of contexts; and converting an input signal of an input channel associated with the second context to a digital signal. - View Dependent Claims (16, 17, 18, 19, 20)
