11.12.2 USIn UART Mode
The universal synchronous and asynchronous serial receiver and transmitter (USART) is a highly flexible serial
communication device. The main features are listed below.
−
Full Duplex Operation (Independent Serial Receive and Transmit Registers)
−
Asynchronous or Synchronous Operation
−
Baud Rate Generator
−
Supports Serial Frames with 5,6,7,8, or 9 Data bits and 1 or 2 Stop bits
−
Odd or Even Parity Generation and Parity Check are Supported by Hardware
−
Data OverRun Detection
−
Framing Error Detection
−
Three Separate Interrupts on TX Completion, TX Data Register Empty and RX Completion
−
Double Speed Asynchronous communication mode
The USIn comprises clock generator, transmitter and receiver. The clock generation logic consists of synchronization
logic for external clock input used by synchronizing or SPI slave operation, and the baud rate generator for
asynchronous or master (synchronous or SPI) operation.
The Transmitter consists of a single write buffer, a serial shift register, parity generator and control logic for handling
different serial frame formats.The write buffer allows continuous transfer of data without any delay between frames.
The receiver is the most complex part of the UART module due to its clock and data recovery units. The recovery unit
is used for asynchronous data reception. In addition to the recovery unit, the receiver includes a parity checker, a shift
register, a two-level receive FIFO (USInDR) and control logic. The receiver supports the same frame formats as the
transmitter and can detect frame error, data overrun and parity errors.
