5.7 RS232 Serial Port
Serial port UART0 is connected to the standard RS232 header fitted to the RSK. Alternatively, serial port UART2
can be connected to the RS232 transceiver by making changes to the configurations to the jumpers and option links
(refer to §6). Connections between the RS232 header and the microcontroller are listed in the
Table 5-5.
