Introduction
• Short latency time due to an arbitration scheme for high-priority messages
• Low power modes, with programmable wake up on bus activity
Furthermore, the new major features below are also provided in addition to the previous
FlexCAN version:
• Remote request frames may be handled automatically or by software
• Safe mechanism for ID Filter configuration in Normal Mode
• CAN bit time settings and configuration bits can only be written in "Freeze" mode
• Tx mailbox status (Lowest priority buffer or empty buffer)
• IDHIT register for received frames
• SYNC bit status to inform that the module is synchronous with CAN bus
• Debug Registers
• CRC status for transmitted message
• Rx FIFO Global Mask register
• Selectable priority of reception between Mailboxes and Rx FIFO during matching
process
• Powerful Rx FIFO ID filtering, capable of matching incoming IDs against either 128
extended, 256 standard or 512 partial (8 bits) IDs, with up to 32 individual masking
capability
• 100% backward compatibility with previous FlexCAN version
48.1.3 Modes of Operation
The FlexCAN module has four functional modes: Normal Mode (User and Supervisor),
Freeze Mode, Listen-Only Mode and Loop-Back Mode. There are also three low power
modes: Disable Mode, Doze Mode and Stop Mode.
• Normal Mode (User or Supervisor):
In Normal Mode, the module operates receiving and/or transmitting message frames,
errors are handled normally and all the CAN Protocol functions are enabled. User
and Supervisor Modes differ in the access to some restricted control registers.
• Freeze Mode:
