I am trying to understand how a micro-controller (in this case a C2000 from TI) communicates with other devices via jtag. The device here is a FT2232 (a jtag to usb converter). According to the figure, would the micro-controller be the "JTAG Controller Connection" and FT2232 the "Device #1"?
I also need to convert the jtag signal to RS-232, and I need to know the directions of jtag. Which channels (TCK, TMS, TDI, TDO) are bi-directional? In other words, does FT2232 (Device #1) ever send a signal to any buses besides TDO?
