Full implementation of the CAN protocol specification version 2.0B
— Standard data and remote frames (up to 109 bits long)
— Extended data and remote frames (up to 127 bits long)
— 0–8 bytes data length
— Programmable bit rate up to 1 Mbps
— Content-related addressing
Up to 32 flexible message buffers of zero to eight bytes data length, each configurable as Rx or Tx,
all supporting standard and extended messages
Listen-only mode capability
Three programmable mask registers: global (for MBs 0–13 and 16–31), special for MB14, and
special for MB15
Programmable transmission priority scheme: lowest ID or lowest buffer number
Time stamp based on 16-bit, free-running timer
Global network time, synchronized by a specific message
Programmable I/O modes
Maskable interrupts
Independent of the transmission medium (an external transceiver is assumed)
Open network architecture
Multimaster bus
High immunity to EMI
Short latency time due to an arbitration scheme for high-priority messages
