The ML675001, system CPLD and user CPLD are all connected to the JTAG chain. The JTAG chain is available from this connector and allows reprogramming of the user CPLD and ICE debugging of the processor.
The JTAG chain on the EB675001DIP is connected to the ML675001, the system CPLD and the user CPLD. Because of this care should be taken to ensure other devices are placed in bypass as required. BSDL files are available from OKI for the ML675001 and Xilinx for the CPLD devices.
