Connector J52 is the PWR connector. Figure 3-4 and Table 3-4 give the pin
assignments and signal descriptions for this connector. This connector accepts
a center positive barrell type power plug with an outside diameter of 5.5mm
and an inside diameter of 2.1mm. The power circuit accepts input voltages
from 6 VDC to 12 VDC and currents up to 0.75 amps.
Background pin used as a pseudo-open-drain pin for background debug
communication
