We are using the design "T1040RDB_Rev_B" for our design reference. I would like to know what is the function of the net "GPIO_CKE_ISO" in this design. 

Also the net is supposed to be working at LVDD 2.5V and the processor is not configured for LVDD 1.8V. What is the reason? I felt that if LVDD was configured for 2.5V the interfacing would have been easier.
