UNIVERSAL SYNCHRONOUS/ASYNCHRONOUS RECEIVER-TRANSMITTER (USART)
The USART is a full-duplex synchronous/asynchronous receiver-transmitter that supports a wide range of software program-
mable baud rates and data formats. It handles automatic parity generation and several error detection schemes. DMA trans-
fers are supported to enable fast processor-independent receive and transmit.
4.9.1
