5.2.1
The RS-232 serial port on the demonstration board incorporates hardware flow control
with CTS and RTS for applications that require these control signalizes makes the port
useful for developing a wide range of serial to USB translators. For those applications
that do not require hardware flow control, or use software flow control instead, the hard-
ware flow control feature can be selectively disabled by cutting the traces at JP4 and
JP6.
Note that the CTS signal and the self-power sense signal share a single controller port
(RA2). These two functions cannot be used concurrently. The CTS is an output signal
from the microcontroller, while the self-power sense signal is an input signal. The port
must be configured either as an input or an output to use each mode. JP6 is provided
to explicitly disable the CTS signal.
