CAN Header Pinout
Both Intel
®
EP80579 Integrated Processor Controller Area Network (CAN) interface
pins connect to two individual CAN transceivers. After conditioning by the transceiver,
the CAN signals will go to two separate 10-pin headers. For the CAN connector pinout,
see
Table 21
.

IEEE 1588-2008 Hardware-Assist Header Pinout
IEEE 1588-2008 Hardware-assist is used to achieve ethernet and CAN time
synchronization. On the Intel
®
EP80579 Development Board, the IEEE 1588-2008
Hardware-assist control I/O signals are connected to a 2x4 header.
Table 22
provides
the IEEE 1588-2008 Hardware-assist header pinout.
