Features
The UART converts data between serial and parallel formats. The serial
format follows an asynchronous protocol that supports various word
lengths, stop bits, and parity generation options. The UART primary fea-
tures are listed below Figure 20-1 on page 20-6 shows the functional
block.
• Compatible with the RS-232 and RS-485 Standards
• Data packing support for efficient memory usage
• Full duplex DMA operation
• Multiprocessor communication using 9 bit addressing
• Autobaud detection support
• The UART includes interrupt handling hardware. Interrupts can
be generated from 12 different events.
The UARTs do not support MODEM functionality.
