3.  Implementation Guide for the CAN Protocol, CAN Specification 2.0 Addendum, CAN In 

Automation, Erlangen, Germany, 1997 

4.  Road vehicles - Controller area network (CAN): Part 1: Data link layer and physical signalling 

(ISO-11898-1, 2003)  

5.  Road vehicles - Controller area network (CAN): Part 4: Time triggered communication (ISO-

11898-4, 2004) 

 

  Supports CAN specification 2.0B

  32 Mailbox version 
  Clock frequency: Up to 36 MHz 
  31 programmable Mailboxes for transmit / receive + 1 receive-only mailbox 
  Sleep mode for low power consumption and automatic recovery from sleep mode by detecting 

CAN bus activity 

  Programmable receive filter mask (standard and extended identifier) supported by all 

Mailboxes 

  Programmable CAN data rate up to 1MBit/s 
  Transmit message queuing with internal priority sorting mechanism against the problem of 

priority inversion for real-time applications 

  Data buffer access without SW handshake requirement in reception 
  Flexible micro-controller interface 
  Flexible interrupt structure 
  16-bit free running timer with flexible clock sources and pre-scaler, 3 Timer Compare Match 

Registers 

  6-bit Basic Cycle Counter for Time Trigger Transmission 
  Timer Compare Match Registers with interrupt generation 
  Timer counter clear / set capability 
  Registers for Time-Trigger: Local_Time, Cycle_time, Ref_Mark, Tx_Enable Window, 

Ref_Trigger_Offset 

  Flexible TimeStamp at SOF for both transmission and reception supported 
  Time-Trigger Transmission, Periodic Transmission supported (on top of Event Trigger 

Transmission) 

  Basic Cycle value can be embedded into a CAN frame and transmitted
