19.5.5 Bus Off State
The bus off state is entered according to the fault confinement rules of the CAN specification. When
returning to CAN operation mode from the bus off state, the module has the following two cases.
In this time, the value of any CAN registers, except registers CiSTR, CiRECR, and CiTECR, does not
change.
(1) When 11 consecutive recessive bits are detected 128 times
(2) When the RetBusOff bit in the CiCTLR register = 1 (Force return from buss off)

The module enters instantly into error active state and the CAN communication becomes possible
immediately.
The module enters instantly into error active state, and the CAN communication becomes possible
again after 11 consecutive recessive bits are detected.
