SN65DP149: DP149 not communication with I2C CTL

Part Number: SN65DP149

HI All,

i am working with a DP149 board, and i m having problems in communication with the device through I2C CTL lines. From microcontroller i can't receive ACK from DP149. My set up is:

I2C set at 100KHz in master microcontroller.

On DP149 pin I2C_EN tied to +3.3V. HDMI_SEL/A1 and EQ_SEL/A0 tied to GND. When i assert OE high, i try to send a packet at address 0xBD, for reading all registers, but i can t get ACK from DP149.

What should i check to see if device is working and connected well??

Thank you.
