3. UART

The UART is a serial I/O port for asynchronous (start/stop) or CLK synchronous communications with external

resources. It has the following characteristics:

• Full duplex double buffering

• Asynchronous (start/stop) or CLK synchronous communications

• Multiprocessor mode support

• Internal dedicated baud-rate generator

Asynchronous

: 19230/9615/31250/4808/2404/1202 bps

CLK synchronous : 2 M/1 M/500 K/250 K bps

• Free baud-rate setting based on external clock

• Error detection functions (parity, framing and overrun)

• Use of NRZ coded transfer signal

• Supports intelligent I/O services
