3. UART1 (SCI)
The UART is a serial I/O port used for CLK asynchronous (start-stop synchronization) communications or for
CLK synchronous (I/O extended serial) communications. The features of this module are described below:
Full-duplex double buffer
CLK asynchronous (start-stop synchronization) communications and CLK synchronous (I/O extended serial)
communications capable
Supports multiprocessor mode
Built-in dedicated baud rate generator
CLK asynchronous: 62500, 31250, 19230, 9615, 4808, 2404 and 1202 bps
CLK synchronous: 2 Mbps, 1 Mbps, 500 Kbps, and 250 Kbps
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
