    USB Serial I2C interface command document?


      I  connected cypd3125 in cy4531 use Micro USB. And I can use I2C API "CyGetI2cConfig" to get configuration. 

      By "CyI2cWrite", I can send I2C command to cypd3125, and hpi_task will deal it. And now I want to send a pd package to cypd3125 by I2C interface, Is there any document what data I need to add in a I2C package, so cypd3125 can regard this I2C package as a pd package and then send to target by cc pin?
