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 cleared automatically.
An interrupt request due to a receive interrupt from the HCAN cannot be sent to the CPU in this
case. Figure 18.15 shows a DTC transfer flowchart.
