Connector J3 is the BDM connector. Figure 2-3 and Table 2-4 give the pin
assignments and signal descriptions for this connector. You can connect
hardware such as P&E’s BDM Multilink to this connector for debugging
purposes.
Table 2-4 BDM Connector J3 Signal Descriptions
Connector J52 is the PWR connector. Figure 2-4 and Table 2-5 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.
