ADRF6801 configuration

Hi, I am trying to configure the ADRF6801 and after reading the data-sheet, it seems that there is no specification of the Register 7. The text describes that Register 7 should be configured first, but there is no documentation about this register.

Also, I am using the ADRF6801 evaluation board. The proper way to provide power is by connecting the VCC test point to a 5V source, or it needs any additional power sources?

Thanks in advance,
