2.3.2. Programmable IOE Delay

You can activate the programmable IOE delays to ensure zero hold time, minimize setup time, or increase clock-to-output time. This feature helps read and write timing margins because it minimizes the uncertainties between signals in the bus.

To ensure that the signals within a bus have the same delay going into or out of the device, each pin can have different delay values:

  • Delay from input pin to input register
  • Delay from output pin to output register

For more information about the programmable IOE delay specifications, refer to the device datasheet.
