it is a "mistake in writing" to describe POWER_BTN# pin.

Hi, Nvidia Guys
On Page 13 in TX1 Datasheet(V1.1), “The only ON EVENT currently
used is a low to high transition on the POWER_BTN# pin.”

I guess it should be “a high to low transition” instead of " low to high transition".
Am I right?

Thanks

‘low to high’ is correct. Please check the figure of power up sequence.

Trumany,

You are right. it means pressing button(POWER_BTN# short to GND) NOT start power up sequence;releasing button DO!
Maybe “#” mislead me.
