The reference manual tells about timeouts etc. but there is no explanation how I can for example make sure that the T4 does NOT immediately boot when powered up, so that the ONOFF button (wired to GND? Pull-up resistor needed?) has to be pressed to boot the Teensy. A forum search for "ONOFF" gave me the 172 page T4 beta thread as a result, but perhaps someone could point me directly to useful info, please?
