26.3.10.1. Error Interrupts

The following error conditions generate interrupts:

  • Bus off—when the transmit error count is equal to or greater than 256, the bus off (BOff) bit in the CAN status register (CSTS) in the protocol group (protogrp) is set to 1.
  • Error warning—when either the transmit error counter or the receive error counters reaches 96, the error warning status (EWarn) bit in the CAN status register (CSTS) in the protocol group (protogrp) is set to 1.
