JTAG need insert Bscan cell between IO and core,
but when JTAG is not used, how to control bscan cell mode, mode_1 signal, etc to normal mode?
I have add pullup resistor to TDI TMS and TRST, but the mode and mode_1 are still X state at normal mode start time.
Does is need a dedicated JTAG mode similliar as Scan mode?
