2.2.2. Programmable IOE Delay
You can activate the programmable IOE delays to ensure zero hold time, minimize setup time, or increase the clock-to-output time. This feature helps read and write timing margins because it minimizes the uncertainties between signals on the bus.
Each pin can have a different input delay from the pin-to-input register or a delay from output register-to-output pin values. This is to ensure that the signals within a bus have the same delay going into or out of the device.
For more information about the programmable IOE delay specifications, refer to the device data sheet.
