17 UART - Universal Asynchronous Receiver/
Transmitter
17.1 Introduction
17.2 Features
2010-09-06 - d0001_Rev1.00
The Universal Asynchronous serial Receiver and Transmitter (UART) is a very flexible serial I/O module.
It supports full- and half-duplex asynchronous UART communication.
• Full duplex and half duplex
• Separate TX / RX enable
• Separate receive / transmit 2-level buffers, with additional separate shift registers
• Programmable baud rate, generated as an fractional division from the peripheral clock (HFPERCLK)
• Max bit-rate
• Asynchronous mode supports
• Configurable number of data bits, 8-9 (plus the parity bit, if enabled)
• Configurable number of stop bits in asynchronous mode: 0.5, 1, 1.5, 2
• HW collision detection
• Multi-processor mode
• Separate interrupt vectors for receive and transmit interrupts
• Loopback mode
0 1 2 3
• UART standard mode, peripheral clock rate / 16
• UART FAST mode, peripheral clock rate / 8
• Majority vote baud-reception
• False start-bit detection
• Break generation/detection
• Multi-processor mode
• HW parity bit generation and check
• Half duplex communication

What?
The UART is capable of high-speed
asynchronous serial communication.
Why?
Serial communication is frequently used in
embedded systems and the UART allows
efficient communication with a wide range of
external devices.
How?
The UART has a wide selection of operating
modes, frame formats and baud rates. The
multi-processor mode allows the UART
to remain idle when not addressed. Triple
buffering and DMA support makes high data-
rates possible with minimal CPU intervention
and it is possible to transmit and receive large
frames while the MCU remains in EM1.
