Hi,


The datasheet is not clear how to configure the HMC1044 and it's not very easy as this chip is write only.


Description of SPI link with 9 bits data, 4 bits reg_addr and 3 bits chip_addr :


 




Next page, description of unique register :


 


I think I have to write directly the 16bits reg value but can you confirm ?




Thanks,
Stéphane
