Details of the I2C Protocol Used by the HX711 I2C Module

Hello,

I want to use the Gravity: I2C 1Kg Weight Sensor Kit - HX711(SKU: KIT0176) with an FPGA by writing a VHDL code to handle I2C communication. But, I need precise details on how this module implements I2C.Do the read and write commands follow a standard I2C approach? What is the exact structure of the I2C protocol used by this module?
