Error active node:
Error passive node: Outputs 6 recessive-level bits consecutively.
If another node outputs a dominant level while one node is outputting a
passive error flag, the passive error flag is not cleared until the same level
is detected 6 bits in a row.
Nodes receiving error flag 1 detect bit stuff errors and issues this error flag.
Outputs 8 recessive-level bits consecutively.
If a dominant level is detected at the 8th bit, an overload frame is
transmitted from the next bit.
The bit at which the error was detected.
The error flag is output from the bit next to the error bit.
In the case of a CRC error, this bit is output following the ACK delimiter.
An interframe space or overload frame starts from here.
