The DEMO9S08AC60E allows the user to power the board in several different 
ways.

The default power option is to power the board through the integrated 
USB-BDM interface. To power the board in this manner, simply connect the 
supplied USB cable from the USB connector on the DEMO9S08AC60E (J33) 
to a USB port on your host computer. LED D1 will light green to let you know 
that power has been correctly applied to the board. When powering the board 
through the USB-BDM interface, jumpers W1, W2, and W3 should be in their 
default position as described below

W1

P_IO_5V

Outputs 5V on pin 1 of 
the I/O connector, J35. 
This jumper should be 
removed if you do not 
want to output 5V on 
this pin.

The DEMO9S08AC60E can also be powered externally through the barrel 
connector J1. This connector is a 2.1 mm, center positive connector. Voltage 
supplied through this connector should be between positive 7 volts and positive 
12 volts DC. To power the board through the external power jack, jumper W2 
should be moved to the 1-2, EXT position. LED D1 will light green to let you 
know that power has been correctly applied to the board. Jumper settings are
