The pushbuttons are not debounced on the UP3 and it's clock frequency
depends on the board's JP3 jumper settings. Set JP3 to short pins 3-4 for the
48Mhz clock. UP3 pins enclosed in parenthesis in table 2.4 are for the larger
FPGA used in the 1C12 version of the UP3 board. It requires more power and
ground pins so there are some minor pin differences. On the UP2 board, the two
pushbuttons are not debounced, the LEDs are the seven segment decimal
points, and its clock is 25Mhz. The original UP1 boards look very similar to a
UP2 and they use the same pin assignments as the UP2, but they contain a
smaller EPF10K20RC240 FPGA.Consult each board's user manual for
additional pin assignments not shown.
