Our customer have used the High-Speed mode for DAC AD5612.
And he has confirmed WRITE and READ action.
After do WRITE action, 1st READ is OK he can catch the correct value, but after 2nd READ he can catch only the 00 value.
Your datasheet show that "The master must then issue a repeated start followed by the device address. The selected
device then acknowledges its address".
Does 00 mean ACK condition?
