How to recalibrate the ADC within 10M08DAF484C8GES on BeMicro board

Hi all, Who knows how to recalibrate the ADC within 10M08DAF484C8GES on BeMicro board? and how to set the following register correctly?

Now I am using altera IP core(14.1) for ADC. There is one register named MODULAR_ADC_SEQUENCER_CSR as follow:

1. When value 0x01 was set, since ADC interrupt was enabled, ADC can produce the data periodly, it seems to work normally.

2. When value 0x03 was set, I expected it could be triggered only one time, but ADC still produced the data periodly, it seems to work abnormally.

3. when value 0x0e was set, I didn't find out recalibration was done.

    I am using the above Be Micro board. I have given it a '7' on the command line and it recals for a short time but then goes back to being not caled. I have issued a reset_n to the ADC module and same thing happens. Not much help from Altera. There is an offset at the input of the ADC, which goes away when the reset is low but then come back when the reset is removed.

    I also need help!!!!!!!!!!!
