iMX.7D JTAG_MOD default pulling

Hello Yuri,

 

removing my pull-up resistor on JTAG_MOD pin solved the problem, which means that the processor sees the unconnected pin as low. Measuring the pin voltage also shows a low pin signal. All this suggests to me that the datasheet table 4 on page 19 is wrong, and that at least the JTAG_MOD pin (haven't tested the other JTAG pins) has an internal on-chip pull-down resistor and NOT pull-up as stated in the datasheet.

 

Can you confirm this?
