Note: This figure uses the CRESET_N and SS_N pins in addition to the standard JTAG pins. However, this setup is only needed for JTAG configuration. You can use the standard four JTAG pins and any cable for other JTAG functions.

When programming T20BGA324, T20BGA400, T35, T55, T85, and T120 s, use this connection:
