Making sure you have the most up-to-date components is the best policy if you are having issues with an older version.
Right-click on the project in the file-tree window and select "Update Components"
I could like to share an I2C example with PSoC4 (CCG is ARM M0 same as PSoC) for your reference. Link: http://www.cypress.com/documentation/code-examples/ce95363-i2c-master-using-serial-communication-block-scb-psoc-4
Of course, if you could like to have an CCGx project example, the CYPD3125 have a I2C master in notebook firmware. You can get a I2C component MUX_CTRL, and then search MUX_CTRL in whole project, you can understand what CCG3 have been done with I2C master and learn it from it. And then, drag a new I2C master component and customize it as per your requiremnets.
BTW, for CCG3 project, please insist to use PSoC Creator 3.3 DP1. Please do not upgrade to the latest one since the GCC compiler is difference with difference PSoC Creator.
I got solution. I2C address provided was not OK. I need to provide right shifted value. And also in read sequence i need not to use repeat flag as per the data sheet. Issue is resoved.
