In an error active and an error passive state, a transmit error count value is stored into the CiTEC register. The
count is decremented when a transmit operation is successfully completed and incremented when a transmit
error occurs.
In a bus-off state, the value in the CiTEC register is undefined. The CiTEC register becomes 00h when the
CAN module is placed in an error active state again.
In an error active and an error passive state, a receive error count value is stored into the CiREC register. The
count is decremented when a receive operation is successfully completed and incremented when a receive error
occurs.
The CiREC register becomes 127 when a receive operation is successfully completed while the CiREC register
equals or exceeds 128 (in an error passive state).
In a bus-off state, the value in the CiREC register is undefined. The CiREC register becomes 00h when the
CAN module is placed in an error active state again.
