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
bit 15-6 Unimplemented: Read as ‘0’
bit 5 TXBO: Transmitter in Error State Bus Off bit (TERRCNT<7:0> > 255)
In Configuration mode, TXBO is set since the module is not on the bus.
bit 4 TXBP: Transmitter in Error State Bus Passive bit (TERRCNT<7:0> > 127)
bit 3 RXBP: Receiver in Error State Bus Passive bit (RERRCNT<7:0> > 127)
bit 2 TXWARN: Transmitter in Error State Warning bit (128 > TERRCNT<7:0> > 95)
bit 1 RXWARN: Receiver in Error State Warning bit (128 > RERRCNT<7:0> > 95)
bit 0 EWARN: Transmitter or Receiver is in Error State Warning bit
