touch screen lcd glass lamination.The JTAG debugging part is composed of 20th pin, 24th pin, 52th pin, 56th pin, 60th pin, and 64th pin. They are TRST, TDI, TMS, TCK, TDO, RTCK . The signal TRST is used as an input to test the reset ; the signal TDI is used as an input to test the data input ; the signal TMS is used as an input to test the mode selection ; the signal TCK is used as an input to test the clock ; the signal TDO is used as an output. The output is used to test data ; the signal RTCK is used as an output and is the returned test clock. Its circuit diagram is as follows:
