(HW)

The implementation is done entirely in hardware. It consists of two parts shown in the Figure 21:

•

A CAN FD light compatible protocol controller with an accurate oscillator for generating and sampling the

data bits.

•

A communication protocol controller that sends and receives data to and from the protocol controller and

controls the communication.

Each responder has its own 9-bit wide ID.
