Section 19 Controller Area Network (RCAN-TL1)
19.6
The DMAC can be activated by the reception of a message in RCAN-TL1 mailbox 0. When
DMAC transfer ends after DMAC activation has been set, flags of RXPR0 and RFPR0 are cleared
automatically. An interrupt request due to a receive interrupt from the RCAN-TL1 cannot be sent
to the CPU in this case. Figure 19.26 shows a DMAC transfer flowchart.
