In an error active or an error passive state, a counting value of the reception error is stored into the
C0REC register. The counter is decremented when the CAN module has received data successfully
or it is incremented when a receive error occurs.
The C0REC register is set to 127 when the C0REC register is 128 (error passive state) or more and
the CAN module has received successfully.
In a bus-off state, an indeterminate value is stored into the C0REC register. The C0REC register is
set to "00

In an error active or an error passive state, the counting value of a transmission error is stored into
the C0TEC register. The counter is decremented when the CAN module has transmitted data suc-
cessfully or is incremented when an transmit error occurs.
