6.9.7
Enhanced Controller Area Network (eCAN) Module
The CAN module (eCAN-A) 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 90 MHz, the smallest bit rate possible is 6.25 kbps.
The F2806x CAN has passed the conformance test per ISO/DIS 16845. Contact TI for test report and
exceptions.
