Figure 16-13. Error Detection Procedures in a Data Frame
The CAN channel can detect some errors on the CAN network.
After detecting an error, the CAN channel sends an error frame on network. If the CAN chan-
nel detects an error frame on network, it sends its own error frame.
The different interrupts are:
The general interrupt enable is provided by ENIT bit and the specific interrupt enable for CAN
timer overrun is provided by ENORVT bit.
• AERR: Acknowledgment error (Tx only). No detection of the dominant bit in the

• In reception:
• Interrupt on receive completed OK,
• Interrupt on transmit completed OK,
• Interrupt on error (bit error, stuff error, CRC error, form error, acknowledge error),
• Interrupt on frame buffer full,

• Interrupt on overrun of CAN timer.
