BITERR[1:0]

RESET:
This register reflects various error conditions, general status, and has the enable bits
for three of the TouCAN interrupt sources. The reported error conditions are those
which have occurred since the last time the register was read. A read clears these bits
to zero.
The BITERR[1:0] field is used to indicate when a transmit bit error occurs. Refer to Ta-
ble D-62.
The ACKERR bit indicates whether an acknowledgment has been correctly received
for a transmitted message.
The CRCERR bit indicates whether or not the CRC of the last transmitted or received
message was valid.
The FORMERR bit indicates whether or not the message format of the last transmitted
or received message was correct.
0 = No ACK error was detected since the last read of this register.
1 = An ACK error was detected since the last read of this register.
0 = No CRC error was detected since the last read of this register.
1 = A CRC error was detected since the last read of this register.
0 = No format error was detected since the last read of this register.
1 = A format error was detected since the last read of this register.

The transmit bit error field is not modified during the arbitration field
or the ACK slot bit time of a message, or by a transmitter that detects
dominant bits while sending a passive error frame.
