M0564
6.19 USCI – UART Mode
6.19.1 Overview
The asynchronous serial channel UART covers the reception and the transmission of
asynchronous data frames. It performs a serial-to-parallel conversion on data received from the
peripheral, and a parallel-to-serial conversion on data transmitted from the controller. The receiver
and transmitter being independent, frames can start at different points in time for transmission
and reception.
The UART controller also provides auto flow control. There are two conditions to wake up the
system.
6.19.2 Features
 Supports one transmit buffer and two receive buffer for data payload
 Supports hardware auto flow control function
 Supports programmable baud-rate generator
 Support 9-Bit Data Transfer (Support 9-Bit RS-485)
 Baud rate detection possible by built-in capture event of baud rate generator
 Supports Wake-up function (Data and nCTS Wakeup Only)
