15.6 DTC Interface
The DTC can be activated by the reception of a message in HCAN2 mailbox 0. When DTC
transfer ends after DTC activation has been set, the RXPR0 and RFPR0 flags are cleared
automatically. An interrupt request due to a receive interrupt from the HCAN2 cannot be sent to
the CPU in this case. Figure 15.15 shows a DTC transfer flowchart.
