15. UART
The UART is a serial I/O port for asynchronous (start-stop) communication or clock-synchronous communication.
The UART has the following features:
Full-duplex double buffering
Capable of asynchronous (start-stop) and CLK-synchronous communications
Support for the multiprocessor mode
Dedicated baud rate generator integratedBaud rate
* : Assuming internal machine clock frequencies of 6, 8, 10, 12, and 16 MHz
Capable of setting an arbitrary baud rate using an external clock
Error detection functions (parity, framing, overrun)
HRz sign transfer signal
