Note: The busoff recovery sequence (see CAN Specification Rev. 2.0) cannot be shortened by setting or resetting the Init
bit. If the device goes in the busoff state, it will set Init of its own accord, stopping all bus activities. Once Init has been
cleared by the CPU, the device will then wait for 129 occurrences of Bus Idle (129 * 11 consecutive recessive bits) before
resuming normal operations. At the end of the busoff recovery sequence, the Error Management Counters will be reset.
During the waiting time after resetting 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.
