Does the GPIO Intel® FPGA IP support dynamic on-chip termination (OCT) control for bidirectional pins?
Description
Workaround/Fix
For applications requiring dynamic on-chip (OCT) control for bidirectional pins, refer to the PHY Lite for Parallel Interfaces Intel FPGA IP Core User Guide.
This additional information is scheduled to be added in a future update of the GPIO Intel® FPGA IP User Guide.
