The bus-off recovery is user configurable. The bus-off state can either be exited automatically or on user
request.
For reasons of backwards compatibility, the MSCAN defaults to automatic recovery after reset. In this
case, the MSCAN will become error active again after counting 128 occurrences of 11 consecutive
recessive bits on the CAN bus (See the Bosch CAN specification for details).
If the MSCAN is configured for user request (BORM set in
(CANCTL1)”), the recovery from bus-off starts after both independent events have become true:
These two events may occur in any order.
