The DTC can be activated by the reception of a message in RCAN-ET mailbox 0. When DTC
transfer ends after DTC activation has been set, flags of RXPR0 and RFPR0 are cleared
automatically. An interrupt request due to a receive interrupt from the RCAN-ET cannot be sent to
the CPU in this case. Figure 19.14 shows a DTC transfer flowchart.
