24.11.4 Slave node, RX mode
On a slave node in RX mode, the DMA interface requires a DMA RX channel for each ID filter
programmed in RX mode. In case a single DMA RX channel is available, a single ID field filter must be
programmed in RX mode. Each TCD controls a single frame, except for the extended frames (multiple
TCDs). The memory map associated to the TCD chain (RAM area and LINFlexD registers) is shown in
.
