MB90220 Series
4. UART1
The UART1 is a serial I/O port for asynchronous communications (start-stop synchronization) or CLK
synchronized communications. It has the following features:
Full-duplex double buffering
Permits asynchronous (start-stop synchronization) and CLK synchronous communications
Multiprocessor mode support
Built-in dedicated baud rate generator
Asynchronous:
9615, 31250, 4808, 2404, and 1202 bps
CLK synchronization: 1 M, 500 K, 250 K bps
Arbitray baud-rate setting from external clock input or internal timer
Error detection function (parity errors, framing errors, and overrun errors)
Transfer in format NRZ
Extended supports intelligent I/O service
