board has completed enumeration on USB.These signals are 3.3 volt, regardless of the host
bus voltage selection.
On pin 9 of connector P1 is output the signal 'Heartbeat'. When the board is working
correctly, this is a toggling signal with a frequency around 2Hz. If a LED is used as an
indicator, it will be blinking.
On pin 10 of connector P2 is output the signal 'Enumerated'. This signal goes high when
the S5U13U00P00C100 enumerated successfully on the USB. If a LED is used as an
indicator, it will turn on upon successful enumeration on the USB.
