Figure 19-13. 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 channel
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.

• 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 “Bus Off” setting,
• Interrupt on overrun of CAN timer.
