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
