DTC Interface
The DTC can be activated by reception of a message in the HCAN's mailbox 0. When DTC
transfer ends after DTC activation has been set, the RXPR0 and RFPR0 flags are acknowledge
signal automatically. An interrupt request due to a receive interrupt from the HCAN cannot be sent
to the CPU in this case. Figure 15-13 shows a DTC transfer flowchart.
