0 = Transmit error counter ≤ 255
TXBP: Transmitter Bus Passive bit
1 = Transmit error counter > 127
0 = Transmit error counter ≤ 127
RXBP: Receiver Bus Passive bit
1 = Receive error counter > 127
0 = Receive error counter ≤ 127
TXWARN: Transmitter Warning bit
1 = Transmit error counter > 95
0 = Transmit error counter ≤ 95
RXWARN: Receiver Warning bit
