5.2.11.4 Now the Pin Planner should look like this after assigning all the pin locations.
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 MAX1000 since all banks and peripherals are

LVTTL. These I/O standards can be set in the Pin Planner, by selecting the I/O Standard. Select

to the specific I/O standard.
