DTC Interface

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