AD9219 operation question

In working with the AD9219, I have a couple of questions regarding some of the settings.


1. Register x21 allow user to set the bit width of the ADC to 8, 10, 12 or 14 bits. I understand AD9219 is a 10bit ADC and the 12 and 14 bits mode will just pad '0's at the end. What about the 8bit mode? is there any performance impact other than the obvious 2bit reduction?


2. Is there a more detailed description of the behavior when I perform a reset using register x08?


3. Does it require a reset or any other additional operations when I change the mode from User test mode to normal operation? register 0D.
