Clearance No.: FTDI#77
4.11 RS232 UART Mode LED Interface Description
When configured in UART mode the FT2232H 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 4.22 Single LED UART Configuration
In Figure 4.22 the transmit and receive LED indicators are wire-ORed together to give a single LED
indicator which indicates any transmit or receive data activity.
Note that the LEDs are connected to the same supply as VCCIO.
