1,As the above table said, if I don't want use JTAG function, should the JTAG_MOD pin be connected with pull-up resistance? what is the resistance ?
2,I also find there are three different JTAG security modes:
Mode #1: No Debug-Maximum Security.
Mode #2: Secure JTAG-High security.
Mode #3: JTAG Enabled-Low security.
I am puzzled about these. I think the JTAG security modes only can be select by burning the related e-fuses if the JTAG_MOD pin is connected to GND.
If we connect the JTAG_MOD pin with pull-up resistance, we can not select the mode. Is my understanding right?
If I don't want to use JTAG function, which method will be recommended?
