Abstract
An isolator that includes first and second substantially identical circuitry galvanically isolated from each other and each having at least one communications channel thereon for communicating signals across an isolation boundary therebetween and each of said first and second circuitry having configurable functionality associated with the operation thereof. A coupling device is provided for coupling signal across the isolation boundary between the at least one communication channels of the first and second circuitry. First and second configuration memories are provided, each associated with a respective one of the first and second circuitry. First and second configuration control devices are provided, each associated with a respective one of the first and second circuitry and each configuring the functionality of the associated one of the first and second circuitry. The first and second configurable memories have stored therein complementary configuration information to control each of the functionalities of the first and second circuitry to operate in a complementary manner for communication of signals across the isolation boundary.

16. A method comprising:
-
storing first configuration information in a first memory to configure a first communication interface to communicate over a galvanic isolation boundary; storing second configuration information in a second memory separate from the first memory to configure a second communication interface to communicate with the first communication interface over the isolation boundary, wherein the storing of the first and second configuration information is performed to configure the first and second communication interfaces to operate in a complimentary manner for communication of signals across the isolation boundary. - View Dependent Claims (17, 18, 19, 20)
