The serial port is based on a Texas Instruments* TL16C550 UART clocked at 1.843 Mhz. The device can be programmed to use this clock with the internal baud rate counters. The serial port can operate at speeds from 300 to 115,200 bps and can be operated in interrupt-driven or polled mode. For a detailed description of the registers and device operation, refer to the TL16C550 documentation (see Table 5, “Documents and Manufacturers” on page 13).
