13.13.6 USART DMA Triggers
There are two DMA triggers associated
with each USART. The DMA triggers are
activated by RX complete and TX
complete events i.e. the same events as
the USART interrupt requests. A DMA
channel can be configured using a USART
Receive/Transmit buffer, UxDBUF, as
source or destination address.
Refer to Table 42 on page 90 for an
overview of the DMA triggers.
13.13.7 USART Registers
The registers for the USART are described
in this section. For each USART there are
five registers consisting of the following (x
refers to USART number i.e. 0 or 1):
• UxCSR USART x Control and Status
• UxUCR USART x UART Control
• UxGCR USART x Generic Control
• UxDBUF USART x Receive/Transmit
data buffer
• UxBAUD USART x Baud Rate Control
