3.2. UART Port
The module also contains a UART port to interface with host board. The UART
implements support for the following features:
• • Full-duplex operation
• • Automatic flow control
• • Parity checking and generation for the 9th data bit
Table 5 shows connections to the UART interface with associated pin numbers.
