recovery sequence, the Error Management Counters will be reset.
(Note)
During the waiting time after the resetting of Init, each time a sequence of 11 recessive bits has
been monitored, a Bit0Error code is written to the Status Register, enabling the CPU to readily
check up whether the CAN bus is stuck at dominant or continuously disturbed and to monitor the
proceeding of the busoff recovery sequence.
