axi_ad9963 no dac_valid output

Hi,

I'm working with AD9963 and I wrote a no-os driver for it.

I used the AD9963 data sheet "EXAMPLE START-UP SEQUENCES" and after that wrote de-assert to axi_ad9963 dac and adc cores (Clock enable / MMCM de-assert / de-assert core).

Reg 0x40 DAC-COMMON and ADC-COMMON: https://wiki.analog.com/resources/fpga/docs/axi_ad9963#adc_channel_axi_ad.

There is no dac_valid or dac_enable.

What can I do do determine what's going wrong?

Thanks for the help,

Amit
