4 bytes in 8-bit data format
•
2 half-words in 16-bit data format
A DMA request is triggered by FIFO not full (TX) status signals.
The concept FSM to control the DMA TX interface is shown in
. DMA TX FSM will move
to idle state if DMATXE[0] = 0.
Figure 24-52. FSM to control the DMA TX interface (UART node)
The TCD settings (typical case) are shown in
. All other TCD fields = 0. The minor loop
transfers a single byte/half-word as soon a free entry is available in the Tx FIFO.
