Claim 13:
14. A method for communication between a microcontroller and at least three sensor chips, each sensor chip of the at least three sensor chips being configured to measure a physical quantity, the method comprising:
conveying, via an analog communication path, analog measurement data from each of the at least three sensor chips and to the microcontroller via a first analog signal interface of the microcontroller and a second analog signal interface of each of the at least three sensor chips; and
conveying, via a digital communication path, digital secondary information between each of the at least three sensor chips and the microcontroller via a first bidirectional digital signal interface of the microcontroller and a second bidirectional digital signal interface of each of the at least three sensor chips, wherein the digital communication path enables the digital secondary information to be conveyed in parallel with the analog measurement data conveyed via the analog communication path.
