MCPLL
TxERC (Tx Error Counter)
TXERC
The Tx Error Counter can only be written to when the CAN Core is
in Reset mode. Hardware will preset the register to 128 when a
Bus–Off condition occurs. See the section entitled Bus Off on page
50 for details.
RXERC
The Rx Error Counter can only be written to when the CAN Core is
in Reset mode. When a Bus–Off condition occurs, this register is
cleared to 00h.
EWLR (Error Warning Limit Register)
EWLR
ECCR (Error Code Capture Register)
ECCR
The Error Code Capture Register contains detailed information
about the most recent Bus Error. See Table 25 for details. The
register must be read in order to be re–enabled for capturing the
next error code, as well as to clear the BERR status flag. This
register should be read before enabling the Bus Error interrupt.
ALCR
The ALCR latches the bit number in the CAN Identifier where the
most recent Arbitration Lost occurred. See Table 26 for details. The
register must be read in order to be reenabled for capturing the next
arbitration lost code, as well as to clear the ARBLST status flag.
