4.3.2.1 Set0.Reg0 - Receiver/Transmitter Buffer Registers (RBR/TBR) (Read/Write)
Receiver Buffer Register is read only and Transmitter Buffer Register is write only. These registers
are described same as legacy UART.
In the legacy UART, this port only supports PIO mode. In the advanced UART, if setup to
MIR/FIR/Remote IR, this port will support DMA handshake function. Two DMA channel can be used,
that is one TX DMA channel and another RX DMA channel. Therefore, single DMA channel is also
supported when set the bit of D_CHSW (DMA Channel Swap, in Set2.Reg2.Bit3) and the TX/RX DMA
channel is swapped. Note that two DMA channel are defined in config register CR2A which select
DMA channel or disable DMA channel. If enable RX DMA channel and disable TX DMA channel, then
the single DMA channel will be selected.
