4.7Enhanced Controller Area Network (eCAN) Modules (eCAN-A and eCAN-B)

The CAN module has the following features:

•Fully compliant with CAN protocol, version 2.0B

•Supports data rates up to 1 Mbps

•Thirty-two mailboxes, each with the following properties:

–Configurable as receive or transmit

–Configurable with standard or extended identifier

–Has a programmable receive mask

–Supports data and remote frame

–Composed of 0 to 8 bytes of data

–Uses a 32-bit time stamp on receive and transmit message

–Protects against reception of new message

–Holds the dynamically programmable priority of transmit message

–Employs a programmable interrupt scheme with two interrupt levels

–Employs a programmable alarm on transmission or reception time-out

•Low-power mode

•Programmable wake-up on bus activity

•Automatic reply to a remote request message

•Automatic retransmission of a frame in case of loss of arbitration or error

•32-bit local network time counter synchronized by a specific message (communication in conjunction with mailbox 16)

•Self-test mode

–Operates in a loopback mode receiving its own message. A "dummy" acknowledge is provided, thereby eliminating the need for another node to provide the acknowledge bit.

NOTE

For a SYSCLKOUT of 100 MHz, the smallest bit rate possible is 15.625 kbps.

For a SYSCLKOUT of 60 MHz, the smallest bit rate possible is 9.375 kbps.
