16.6.4 Stamping Message
The capture of the timer value is done in the MOb which receives or sends the frame. All managed MOb are stamped, the
stamping of a received (sent) frame occurs on RxOk (TXOK).

Error Management
16.7.1 Fault Confinement
The CAN channel may be in one of the three following states:
●
Error active (default):
The CAN channel takes part in bus communication and can send an active error frame when the CAN macro detects an
error.
●
Error passive:
The CAN channel cannot send an active error frame. It takes part in bus communication, but when an error is detected, a
passive error frame is sent. Also, after a transmission, an error passive unit will wait before initiating further transmission.
●
Bus off:
The CAN channel is not allowed to have any influence on the bus.
For fault confinement, a transmit error counter (TEC) and a receive error counter (REC) are implemented. BOFF and ERRP bits
give the information of the state of the CAN channel. Setting BOFF to one may generate an interrupt.

Note:
More than one REC/TEC change may apply during a given message transfer.
