Figure 18-54:
Bus-Off recovery (Except Normal Operation Mode with ABT)
Note:
Clear all TRQ bits when re-initialization of message buffer is executed by clearing RDY bit
before bus-off recovery sequence is started.
Caution:
When the transmission from the initialization mode to any operation modes is
requested to execute bus-off recovery sequence again in the bus-off recovery
sequence, reception error counter is cleared.
Therefore it is necessary to detect 11 consecutive recessive-level bits 128 times on
the bus again.
Remark:
OPMODE: Normal operation mode, normal operation mode with ABT, receive-only mode,
single-shot mode, self-test mode
