7.5.1 CAN Features
Document Number: 001-55036 Rev. *A
CAN2.0A/B protocol implementation - ISO 11898 compliant
Listen Only mode
SW readable error counter and indicator
Sleep mode: Wake the device from sleep with activity on the
Rx pin
Supports two or three wire interface to external transceiver (Tx,
Rx, and Enable). The three-wire interface is compatible with
the Philips PHY; the PHY is not included on-chip. The three
wires can be routed to any I/O
Enhanced interrupt controller
Standard and extended frames with up to 8 bytes of data per
frame
Message filter capabilities
Remote Transmission Request (RTR) support
Programmable bit rate up to 1 Mbps
CAN receive and transmit buffers status
CAN controller error status including BusOff
