Description
Sets the board for 5V
operation
Sets the board to be
W2
1-2
EXT
powered externally
through J1
Outputs 5V on pin 1 of
the I/O connector, J35.
W3
1-2
P_IO_5V
This jumper should be
removed if you do not
want to output 5V on
this pin.
1.9.3 I/O Connector
The DEMO9S08AW60E 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
