Figure 4.11 shows a recommended circuit for external LED connection to Ready LED output signal.

Figure 4.11 Recommended external circuit for Ready LED output

Either +3.3 V or +5 V can be used for external power supply for LED (Vcc). Current limiting resister (R) value need to be adjusted depend on the Vcc voltage. For +3.3 V Vcc voltage, recommended resistance is 220 Ω. For +5 V Vcc voltage, recommended resistance is 330 Ω.
