bit 7
bit 0
bit 7
ESCF: Error State Change (for sending Error state message)
1
= An error state change occurred
0
= No error state change
bit 6
RBO: Receive Buffer Overflow
1
= Overflow occurred
0
= No overflow occurred
bit 5
TXBO: Transmitter in Bus Off Error State bit
1
= TEC reaches 256
0
= Indicates a successful bus recovery sequence
