AVR32768
13 CAN interface
The UC3 C embeds a CAN controller, which generates and handles digital
transmission and reception signals TXD and RXD. These signals can be used to
interface a CAN line driver, which generates the physical differential signals on the
CAN bus. Figure 13-1 shows an example schematic using the Atmel AT6660 high-
speed CAN transceiver.
Usage of the CAN interface is detailed in the application note, AVR32129: Using the
32-bit AVR UC3 CANIF.
