Now the Pin Planner should look like this after assigning all the pin locations.
5.2.12.5
The specific pins are now selected, but the I/O standards now need to be set as well. The
button, LEDS, and clock pins are the same I/O standard for C10LP RefKit since all banks
and peripherals are powered by 3.3V. The USER_BTN, the LEDs and clock pins are 3.3-V
LVTTL. These I/O standards can be set in the Pin Planner, by selecting the I/O Standard.
Select the I/O standard either from the
“
All Pins
”
tab or the
“
Groups
”
tab and change
the 2.5V (default) to the specific I/O standard.
