TPS25751: TPS25751D : EEProm update code example issue

Tool/software:

Hi,

I currenty just designed a board with a TPS25751D, whose I2Ct bus is connected to an MCU, and the I2Cc bus is connected to an EEProm and to a BQ25792.

I am trying to write a code for the MCU which can update the EEProm content in order to load the correct configuraition on the TPS25751D on boot, based on the "TPS25751 and TPS26750 EEPROM Update Over I2C" application note : https://www.ti.com/lit/an/slvafl1/slvafl1.pdf?ts=1740676504703

However in the source code example several struct types and macros are not explicitly defined, which prevents me from writing the c driver : 

Could you please tell me where I can find the definitions of these structs and macros ?

Best regards,

Guillaume
