output power of AD9361

1.   How do I control the output power of AD9361?  Different digital data are sent  to AD9361, from 0x000 to 0xFFF, the output level of DAC should vary from 0dBFS to 72 dBFS, but the output power of AD9361 did not change, is there any auto level control circuitry within the AD9361? How does it work?
2.   We try to modify the register via the valuation platform composed of Evaluation board AD-FMCOMMS2-EBZ and ZYNQ-7000, but we failed, is the function of modifying the registers supported by the evaluation boards mentioned above? If the answer is yes, how?
3.   What is the minimum time require by AD9361 to switch the frequency. The time to switch the frequency means the time interval starts from the beginning of a SPI command transmission to when the AD9361 settles <1% freq error on the newly requested freq.
4.   If the input RF power exceeded the absolute max input power 2.5dBm, what kind of failure would happen? Power failure of voltage failure?
