Hello support team,
Our customer is evaluating DAC5687 now.
The following phenomenon is occurring in customer's evaluation environment.
He can not write into three addresses of CONFIG0 (0x01), CONFIG1 (0x02), CONFIG2 (0x03).
Even if he wrote, the data of three addresses will be fixed with the value of the read data.
CONFIG0 (0×01): 0×80
CONFIG1 (0x02): 0x00
CONFIG2 (0x03): 0x00
He had confirmed that the other registers can be written and read.
Questions;
Is there possible reasons why he can not write into these three registers?
Are there any conditions necessary to write into these three registers?
Best regards,
M. Tachibana
