I am using two AD5724 in daisy chain mode, and I have no problem to write to the DACs, but I could not read back from them.
Once I try to read, the device stop responding to what I write.
I am using the fllwoing sequnce in software:
Write to all DAC registers ( DAC output responding)
Send 0x800000 0x800000 (48 bit) through SPI to enable the read mode
Send NOP 0x180000 0x180000 (48 bit) to read DAC0 in both chips
At this point if I try to write anything the device will not respond, am I reading in a wrong way?
