MCU and ad1701 through the I2C communication, I write the dsp core control register (0x081c):a[2]={0x00,0x1c},the dac register b[2]={0x00,0x01}。I read the dsp core control register data is 0x00,0x1c,the dac register data is 0x00,0x01.when I through adc0 and adc1 input analog signals，why the dac2 and dac3 have not output?I follow this ad1701 data manual configuration
See below：
the default program signal flow
Don't I have a hardware problem?
