I use indirect JTAG programming. Attached is the schematic how I connected the JTAG

1) Since the VCCIO for bank contained data0 (Bank1C) is connected to 1.5V; therefor, I follow your instruction to add resistor divider. How do I connect these resistors?

2) From schematic, do I connect JTAG pin 4 correctly? Should I change these 2.5V to 3.3V?

Thanks
