Saleh, [quote userid="593855" url="~/support/data-converters-group/data-converters/f/data-converters-forum/1431288/amc131m03-spi-communication-with-the-device/5504921#5504921"]what are you trying to configure with your first write[/quote] I am configuring MODE for 24 bits SPI with timeout and CLOCK for High resolution, oversampling ratio of 256 and enabling all 3 channels. I am doing it mainly to check communication but also because I was thinking that configuration should be done first before I can enable DC/DC. Thank you for checking my commands. I am clearly adding bit incorrectly. I believe it should be 0x610200 0x011000 0x0070E00 0x000000 0x000000 to configure MODE, CLOCK and GAIN registers. It would help to have examples of command calculations somewhere in the datasheet to verify understanding of the document.

({0x788000,0x000100,0x000000,0x000000,0x000000})[/quote] I did not know I can do it without configuring the device first. Unfortunately, even after I send the above command immediately after reset, I do not see any change on the DCDC_OUT line: Is there something else I can try?
