42.1.2 FlexCAN Module Features
The FlexCAN module includes these distinctive legacy features:
• Full Implementation of the CAN protocol specification, Version 2.0B
• Standard data and remote frames
• Extended data and remote frames
• Zero to eight bytes data length
• Programmable bit rate up to 1 Mb/sec
• Content-related addressing
• Flexible Mailboxes of zero to eight bytes data length
• Each Mailbox configurable as Rx or Tx, all supporting standard and extended
messages
• Individual Rx Mask Registers per Mailbox
• Full featured Rx FIFO with storage capacity for up to 6 frames and automatic
internal pointer handling
• Transmission abort capability
• Programmable clock source to the CAN Protocol Interface, either bus clock or
crystal oscillator
• Unused structures space can be used as general purpose RAM space
• Listen-only mode capability
• Programmable loop-back mode supporting self-test operation
• Programmable transmission priority scheme: lowest ID, lowest buffer number or
highest priority
• Time Stamp based on 16-bit free-running timer
• Global network time, synchronized by a specific message
• Maskable interrupts
• Independent of the transmission medium (an external transceiver is assumed)
