• Manufacturer Part Number: HI-3110
• Description: Avionics CAN Controller with Integrated Transceiver
• Manufacturer: HOLTIC [Holt Integrated Circuits]

The ERR register indicates CAN bus status and protocol errors. It is read only. All bits default to 0 at power up and maintain their
current status following reset. Bits 4:0 are reset following a host read.

Bus-off status indicator.
This bit is set when TEC > 255. Node is in bus off condition. The bit is reset by HI-3110 when a
successful bus recovery sequence is detected (128 x 11 consecutive recessive bits). d the
FILHIT3:0 bits will reflect this value.
Transmit Error Passive status indicator.
This bit is set when 128
Receive Error Passive status indicator.
This bit is set when 128
Bit Error.
A bit error was detected in a transmitted frame (the bit observed on the bus was opposite to
what was expected).
Form Error.
A Form error was detected in a receive frame.
CRC Error.
A CRC error was detected in a receive frame.
Acknowledgement Error.
An ACK error was detected in a receive frame.
Stuff Error.
A bit stuffing error was detected in a received frame.
