The transmitter section accepts SPI/MICROWIRE data,

formats it, and transmits it in asynchronous serial format

from the TX output. Data is loaded into the transmit-

buffer register from the SPI/MICROWIRE interface. The

MAX3100 adds start and stop bits to the data and

clocks the data out at the selected baud rate (Table 7).
