Hi Meran,
Yes, you can. There are some registers can be accessed by I2C. And Cypress owned a documentation which list out related registers and the way you need to communicate with CCG2. The best way to get the documentation is contact your local FAE. If you have not been contacted local Cypress, feel free to select one of them to contact it.

Meanwhile, you could get all of API of CCGx firmware from SDK API user guide. LINK: http://www.cypress.com/documentation/software-and-drivers/ez-pd-software-development-kit?source=sear...
