AD5235 PROBLEMS EEPROM ACCESS

Hi,

I have problems when reading out the user EEPROM via SPI on AD5235.

The Problems occur sporadically when read the address 0x1 or 0x2. All other Address can be read easily.

I will explain the problems by reading the address 0x1.

The Master sends the following command to read out:

CMD_Master_Read_Adress_0x01.png

After 35ms the Master send a NOP call to get the value from the EEPROM address 0x1.

The AD5235 sends back an incorrect value.

CMD_Slave_send_Address_0x02.png

Does anyone have a suggestions for a solution of this problem?
