Hi,
I have two AD5410 in daisychain configuration.
For initialization, I'd like to perform a software reset as described in the datasheet (fig. 40), as I can't tell in which state the devices are (maybe some previous config maybe some unknown powerup).
As far as I understand the daisychain mode, the reset command 0x560001 has to be sent in one 24bit-command to the first device and toggled to the 2nd device by sending NOP 0x000000. With an additional NOP, the 0x560001 should appear at SDO (for a possible next device or a readback for verification of the communication).
However, only the first device seems to get the command:
Other commands seem to get passed correctly from SDI to SDO in the next command.
How can I do the software reset of all devices in the daisy chain?
If the devices are in standalone-mode (which they should be the first time the initialization is done), any command with multiples of 24bit should be ignored, so sending the software reset in daisychain mode should have no effect, but it seems that the reset command itself is not forwarded to the next device (maybe the output shift register is also cleared) - I don't have an idea how to get through this problem
Best regards,
Simon
