SGTL5000 MIC BIAS pin

Hello, I'm using SGTL5000 codec (QFN20) with micro input.

I have a question about typical application schematic (figure 20 in datasheet).

How must I connect MIC BIAS pin if I use the internal bias resistor?

Internal bias resistor is connected between internal MIC bias voltage and MIC_BIAS pin (pin 11 on 20QFN package). Am I right?

Best Regards.
