Abstract: Described embodiments provide a device configured to be coupled to a shared bus. The device includes a magnetic field sensing element to sense a magnetic field. Upon receiving a configuration command over the shared bus, the device determines whether a parameter of the sensed magnetic field meets a predetermined criteria. If the parameter of the sensed magnetic field meets the predetermined criteria, the device responds to the configuration command by applying one or more configuration settings. Otherwise, if the parameter of the sensed magnetic field does not meet the predetermined criteria, the device ignores the configuration command.

Abstract: A network slave device includes a transceiver for communicating over a communication bus in accordance with a point-to-point network protocol. The network slave device may have an address to identify the network slave device on the network. It may also have a communication circuit configured to process a series of commands received by the transceiver and respond to a command if a position of the command in the series of commands corresponds to the address of the network slave device. A master device communicating on the network may send the series of command in accordance with the point-to-point network protocol. In an embodiment, the point-to-point protocol is the SENT protocol.

Abstract: In one aspect, a system includes a master component having a communication node; and a plurality of slave components. Each slave component has a bidirectional node. The slave components are configured to each store data in response to a trigger signal received at the bidirectional node from the communication node.

Abstract: An integrated circuit can have a first substrate supporting a magnetic field sensing element and a second substrate supporting another magnetic field sensing element. The first and second substrates can be arranged in a variety of configurations. Another integrated circuit can have a first magnetic field sensing element and second different magnetic field sensing element disposed on surfaces thereof.
