SN65DP159: I2C Program setting method.

Hironori Yoshimura
Intellectual 1850 points
Part Number: SN65DP159

I refer slla468.pdf  Page# 1 ChooseI2C modeor pin-strap mode via I2C_EN:  and Chosing I2C_EN is high.
I understand that EQ_SEL/A0 , HDMI_SEL/A1 are controling DP159 I2C slave address.

If my customer would lide to set Address into BC, please kindly share required power seq/control method ?
I carefully looked datasheet or apps note but I could not find right procedure.

    Hi,

    I2C_EN needs to be pulled up to 3.3V through a 65k resistor

    Both A0 and A1 need to be pulled to ground through separate 65k resistor.

    Once the DP159 powers up and sample the state of the I2C_EN, A0, and A1 pin, the DP159 will be in I2C mode with the correct I2C address.

    Thanks
