I am trying to setup the adv7513 using a PSOC3. The PD/AD pin is tied low, so I use 0x72 as the slave address. I want to write on to the base address 0x48 with data 0x00 and base address 0x15 with data 0x03. The timing and the data on the I2C bus looks right but I do not get any ACK. I have also made sure to have a delay of 200ms before trying to communicate through the I2C. I have attached the timing I get from the Logic Analyser.

Let me know if I am doing something wrong. Thanks
