The firmware takes care of the inversionand returns the correct data.Note that this only applies to the JTAG-USB cable, and not the JTAG-HS series.The JTAG-HS is based on FTDI chips, not the Cypress FX2. The TDO lineis level-shifted through a single transistor, which results in the TDO signalbeing inverted as it enters the FX2.

I don't have detailed schematics available my testsetup consists of a FX2 on a custom board where it's directly connected to aCyclone FPGA. Once I had a version that could be compiled with Keil tools (until early2007), but switched to SDCC because I usually develop on a Linux host.No logic beside the FX2 itself and only a few external components are requiredfor a basic JTAG adapter.
