Ready LED output signal

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 . For +5 V Vcc voltage, recommended resistance is 330 .
