4.4

Enhanced Controller Area Network (eCAN) Module

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 150 MHz, the smallest bit rate possible is 23.4 kbps.

The 28x CAN has passed the conformance test per ISO/DIS 16845. Contact TI for details.
