A program to test SGPIO with CPLD passthrough Input & Output via the SGPIO CPLD interface (P8 BANK2_AUX). For this test connect P10 BANK1_AUX AUX9 pin to +1V8 (in order to have P8 BANK2_AUX AUX1 to 16 as Output). This test requires: * JellyBean+Lemondrop(to set clock at 204MHz). * CPLD X2C64A hardware\jellybean\sgpio_if_passthrough\sgpio_if_passthrough.svf to be loaded first.
