9. LED Interface
Any of the 5 CBUS I/O pins can be configured to drive an LED. The FT232R has 3 options for driving an LED - these
are TXLED#, RXLED#, and TX&RXLED#.

Figure 19 illustrates the configuration where one pin is used to indicate transmission of data (TXLED#) and another
is used to indicate receiving data (RXLED#). When data is being transmitted or received the respective pins will drive
from tri-state to low in order to provide indication on the LEDs of data transfer. A digital one-shot time is used so that
even a small percentage of data transfer is visible to the end user.
Figure 20 -Single LED Configuration
In figure 20 the TX&RXLED CBUS option is used. This option will cause the pin to drive a single LED when data is
being transmitted or received by the device.
