AD5241 Digital Potentiometer problem

  I am having problem in I2C communication with AD5241. The slave device address is 0x58 (for write) and 0x59 (for read).

The problem i am facing is when i am sending the slave address, the device is sending ACK but when i send the instruction byte(0x00) the device is sending NACK.

I am able to read the RDAC value in read mode. But i am unable to write any value to RDAC. What might be the instruction byte should i send.? Please help me with the issue. Thanks.
