2.5.3.2. Enabling Dual-Purpose Pins
AVST_CLK, AVST_DATA[15:0], AVST_DATA[31:16], AVST_READY, and AVST_VALID are dual-purpose pins. Once the
device enters user mode these pins can function either as GPIOs or as tri-state inputs.
If you use these pins as GPIOs, make the following assignments:
• Set V
CCIO
of the I/O bank at 1.2 V
• Assign the 1.2 V I/O standard to these pins
Complete the following steps to assign these settings to the dual-purpose pins:
1. On the Assignments menu, click Device.
2. In the Device and Pin Options dialog box, select the Dual-Purpose Pins category.
3. In the Dual-purpose pins table, set the pin functionality in the Value column.
4. Click OK to confirm and close the Device and Pin Options
Attention: When you use the Avalon ST configuration scheme the dual-purpose Avalon ST pins have the following
restrictions:
• You cannot use the Avalon-ST interface for partial reconfiguration (PR).
• You cannot use the Avalon-ST pins in user mode in designs that include the HPS. This restriction means that you
cannot use the Avalon-ST as dual-purpose I/Os in designs that include the HPS.
