Hello,

 

While observing the ACE Macro SPI Read/Write commands using ACE Macro with AD9164+ADS7_v2 Evaluation Setup.

There were SPI writes to many registers which are not mentioned in the DS.

What is the purpose of these commands and are they really required for the DAC setup?

Could you pleaes clarify?
