Figure 8.5 Single LED Configuration
When configured in UART mode the FT2232D has two IO pins on each channel dedicated to controlling
LED status indicators, one for transmitted data the other for received data. When data is being
transmitted / received the respective pins drive from tri-state to low in order to provide indication on the
LEDs of data transfer. A digital one-shot timer is used so that even a small percentage of data transfer is
visible to the end user. Figure 8.4 shows a configuration using two individual LEDs – one for transmitted
data the other for received data. In Figure 8.5, the transmit and receive LED indicators are wire-ORed
together to give a single LED indicator which indicates any transmit or receive data activity.
Another possibility (not shown here) is to use a 3 pin common anode tri-color LED based on the circuit in
Figure 7.5 to have a single LED that can display activity in a variety of colors depending on the ratio of
transmit activity compared to receive activity.
Note that the LEDs are connected to the same supply as VCCIO.
