Signaling between master and slave components using a shared communication node of the master component
First Claim
1. A network slave device comprising:
- a transceiver for communicating over a communication bus in accordance with a point-to-point unidirectional network protocol, wherein the point-to-point unidirectional network protocol is a single edge nibble transmission (SENT) protocol;
an address of the network slave device to identify the network slave device; and
a communication circuit configured to process a command received by the transceiver and generate a reply for transmission over the communication bus if an address included in the command matches the address of the network slave device, wherein the network slave device comprises a magnetic field sensor.

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 include an address to identify the network slave device on the network. It may also include a communication circuit configured to process a command received by the transceiver and generate a reply for transmission over the communication bus if an address included in the command matches the address of the slave device. A master device communicating on the network may send commands including the address of the slave device in accordance with the point-to-point network protocol. In an embodiment, the point-to-point protocol is the SENT protocol.
