GZ logic level shifter testing notes

Now I have soldered half of the 16 bit 3V3 to 5V0 logic level up shifter.  I am testing gz_test with 1 MHz clock input to GPCLK0 of GuzuntyPi.  I used 2 4 wire cables to connect 8 pins from GZ to 8 pins of the level shifter.  The LED indicators of the logic level shifter displays the group of 8 stage binary counters and everything looks OK.

Now I think it is time to end the gz_test experiment and move on to the next XC9572XC core, the 16o8i core.
