ESCF RBO TXBO TXEP RXEP TXWAR RXWAR EWARN

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

bit 4 TXEP: Transmitter in Error Passive State bit

1 = TEC is equal to or greater than 128

0 = TEC is less than 128

bit 3 RXEP: Receiver in Error Passive State bit

1 = REC is equal to or greater than 128

0 = REC is less than 128

bit 2 TXWAR: Transmitter in Error Warning State bit

1 = TEC is equal to or greater than 96

0 = TEC is less than 96

bit 1 RXWAR: Receiver in Error Warning State bit

1 = REC is equal to or greater than 96

0 = REC is less than 96

bit 0 EWARN; Either the Receive Error counter or Transmit error counter has reached or exceeded

96 errors

1 = TEC or REC is equal to or greater than 96 (TXWAR or RXWAR = 1)

0 = Both REC and TEC are less than 96

Legend:

R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’

- n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
