ADAU1772 and ADAU1777, can the SELFBOOT pin be connected to GND directly?

Question

Hi, 
 The ADAU1772 and ADAU1777. When we don't use the self boot, can we connect the SELFBOOT pin to DGND without resister? Or should we use a resistor? I thought that either is OK, but please let me confirm. 
 Several Audio codec and Sigma DSP products support the self boot, and each device has the SELFBOOT pin. I checked descriptions about the SELFBOOT pins and found below. 
 ADAU1772, ADAU1777 Pull this pin up to IOVDD at power-up to enable the self-boot mode. 
 ADAU1787 Connect this pin to IOVDD at power-up to enable the self boot mode. Otherwise, set this pin to DGND at startup. 
 ADAU1701 This pin can be tied directly to the control voltage or pulled up/down with a resistor. 
 ADAU146x This pin can be connected to IOVDD or to ground either directly or pulled up or down with a 1.0 kΩ or larger resistor.

Hello Euglena, 
 You can tie it directly to ground with no problems. If you want to use a resistor then I would suggest 10K or smaller.
