The EMAC module implements a 10/100 Ethernet MAC compatible with the IEEE 802.3 standard using
an address checker, statistics and control registers, receive and transmit blocks, and a DMA interface.
The SAM3X-EK is equipped with a Davicom DM9161AEP 10/100 Mbps Fast Ethernet Physical Layer
TX/FX Single Chip Transceiver. It contains the entire physical layer functions of 100BASE-TX as defined
by IEEE 802.3u, including the Physical Coding Sublayer (PCS), Physical Medium attachment (PMA),
Twisted Pair Physical Medium Dependent Sublayer (TP-PMD), 10BASE-TX Encoder/Decoder
(ENC/DEC), and Twisted Pair Media Access Unit (TPMAU).
The Ethernet interface provides RMII (Reduced MII), for 100Base-TX or 10Base-TX. The RMII interfaces
are capable of both 10Mb/s and 100Mb/s data rates as described in the IEEE 802.3u standard.
The Ethernet interface integrates an RJ45 connector with an embedded transformer, and three status
LEDs. For guarantee DM9161AEP is reset properly, a reset IC MN19 is integrated too.
The CAN controller provides all the features required to implement the serial communication protocol
CAN defined by Robert Bosch GmbH, the CAN specification as referred to by ISO/11898A (2.0 Part A
and 2.0 Part B) for high speeds and ISO/11519-2 for low speeds. The CAN Controller is able to handle
all types of frames (Data, Remote, Error and Overload) and achieves a bit rate of 1 Mbit/sec.
The SAM3X8H has two CAN Controllers with eight Mailboxes.
