I want to clarify is it mandatory to set low TRST_N , (when we do not use JTAG) after power-up?
The datasheet recommends the next:
Is it necessary? Can I connect MODE[2:3] and TRST_N pins and left this line floating?The TRST_N pin must be asserted low during and after power up for 100 ns. If JTAG is not required, the TRST_N pin can be tied to ground to hold the JTAG module in reset.
Could somebody advise.
Thank You.
