The J1 controls the way in which the Connect ME 9210 JTag device responds to pin 14
being pulled low.
The embedded modules support a hardware reset on pin 14 of the 20-pin header. Pulling
pin 14 low with an open drain driver will force the module into a hard reset state. The
module will remain in the reset state as long and pin 14 is held low and will leave this reset
state ~250mS after pin 14 goes high. Do not actively drive pin 14 high and do not allow the
rise time of the pin 14 to be longer than 100uS. When used with the development board,
this pin is wired to reset button SW4, which means it acts as a hard reset button.
