1.9.3 I/O Connector
The DEMO9S08AC60E can also be powered through pin 1 of the I/O connector J35. To power the board in this manner the jumper on W2 should be removed and positive 5V DC should be applied on pin 1 of J35. This voltage input is not regulated on the board so care should be taken to provide a clean 5V signal.
LED D1 will light green to let you know that power has been correctly applied to the board. Jumper settings are detailed below
