1.5.3.9. Determine if you need to turn on device-wide output enable

The MAX® 10 device supports an optional chip-wide output enable that allows you to override all tri-states on the device I/Os. When the DEV_OE pin is driven low, all I/O pins are tri-stated; when this pin is driven high, all pins behave as programmed.

To use the chip-wide output enable feature:

  • Turn on Enable device-wide output enable (DEV_OE) under the General category of the Device and Pin Options dialog box in the Quartus® Prime software before compiling your design
  • Ensure that the DEV_OE pin is driven to a valid logic level on your board
  • Do not leave the DEV_OE pin floating
