2. UART
The UART is a serial I/O port for CLK asynchronous (start-stop synchronization) communications or for CLK
synchronous communications. The features of this module are described below:
Full-duplex double buffer
CLK asynchronous (start-stop synchronization) communications and CLK synchronous communications
capable
Supports multiprocessor mode
Built-in dedicated baud rate generator
Permits setting of any desired baud rate according to an external clock input
Error detection function (parity errors, framing errors, and overrun errors)
NRZ code as transfer signal
Supports Intelligent I/O Service
(1) Register Conguration
CLK asynchronous: 9615, 31250, 4808, 2404, 1202 bps
CLK synchronous: 1 M, 500K, 250K, 125K, 62.5K bps
For a 6, 8, 10, 12, or 16 MHz clock.
