When you use RT OCT, adhere to the maximum allowed duration for enabling the RT OCT based on pin utilization per I/O bank.
This guideline applies to the following I/O standard when operating in GPIO or PHY Lite modes:
- SSTL-12 and Differential SSTL-12
- HSTL-12 and Differential HSTL-12
- HSUL-12 and Differential HSUL-12
