The CAN performs communication according to the CAN protocol version 2.0 part A and B. The bit rate can be
programmed to values up to 1MBit/s. For the connection to the physical layer additional transceiver hardware
is required.

The CAN implements the following features:

• Supports CAN protocol version 2.0 part A and B

• Bit rates up to 1 MBit/s

• 32 (up to 128) Message Objects

• Each Message Object has its own identifier mask

• Programmable FIFO mode (concatenation of Message Objects)

• Maskable interrupt

Disabled Automatic Retransmission mode for Time Triggered CAN applications

• Programmable loop-back mode for self-test operation
