RXB0OVFL: Receive Buffer 0 Overflow bit
1 = Receive Buffer 0 overflowed
0 = Receive Buffer 0 has not overflowed
RXB1OVFL: Receive Buffer 1 Overflow bit
1 = Receive Buffer 1 overflowed
0 = Receive Buffer 1 has not overflowed
TXBO: Transmitter Bus-Off bit
1 = Transmit Error Counter > 255
0 = Transmit Error Counter ≤ 255
TXBP: Transmitter Bus Passive bit
1 = Transmission Error Counter > 127
0 = Transmission Error Counter ≤ 127
RXBP: Receiver Bus Passive bit
1 = Receive Error Counter > 127
0 = Receive Error Counter ≤ 127
TXWARN: Transmitter Warning bit
1 = 127 ≥ Transmit Error Counter > 95
0 = Transmit Error Counter ≤ 95
RXWARN: Receiver Warning bit
1 = 127 ≥ Receive Error Counter > 95
0 = Receive Error Counter ≤ 95
EWARN: Error Warning bit
This bit is a flag of the RXWARN and TXWARN bits
1 = The RXWARN or the TXWARN bits are set
0 = Neither the RXWARN or the TXWARN bits are set
