NOTES:
17. During Calibration xCCCC (MSB justified) is presented at the output data bus, toggling on the LSB (and higher) data bits occurs at completion of
calibration. This behavior can be used as an option to determine calibration state.
18. Use test_io = 0x41 for Checkerboard outputs on DDR Outputs.
19. Use test_io = 0x71 for all ones/zeroes outputs on DDR Outputs.
