Digital Signal Processors
SPRS230F–OCTOBER 2003–REVISED SEPTEMBER 2005
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 15.6 kbps.
