It is logic 1 in the first message (‘sign-on’ message) after the successful detection of the bit rate
(bit time calibrated).
Logic 1, if the error warning limit (32) is reached. In the “sign-on” message EW is always logic 1. The
EW status bit is set when the Receive Error Counter or the Transmit Error Counter have exceeded the
Error Warning Limit of 32, also temporarily, since the last successful transmission of a message.
Bus mode status bits.
