5 V, 2.2 V and 2.5 V dual UART, 5 Mbit/s (max.), with 64-byte FIFOs
6.6 DMA operation
There are two modes of DMA operation, DMA mode 0 or DMA mode 1, selected by
FCR[3].
In DMA mode 0 or FIFO disable (FCR[0] = 0) DMA occurs in single character transfers. In
DMA mode 1, multi-character (or block) DMA transfers are managed to relieve the
processor for longer periods of time.
6.6.1 Single DMA transfers (DMA mode 0/FIFO disable)
Figure 10 shows TXRDYn and RXRDYn in DMA mode 0/FIFO disable.
6.6.1.1
Transmitter
When empty, the TXRDYn signal becomes active. TXRDYn will go inactive after one
character has been loaded into it.
6.6.1.2
Receiver
RXRDYn is active when there is at least one character in the FIFO. It becomes inactive
when the receiver is empty.
