9.9. Power Supply Selector (J2)
The C8051F064 evaluation board can be powered from either the DEBUG or DATA ports through the USB
connection. The J2 header allows the user to select between these ports. Each configuration includes an on-board
voltage regulator to supply 3.3 V to the board. To power the 3.3 V supply from the DATA port, place a shorting block
on J2, Pin 1 and Pin 2. To supply the 3.3 V supply from the DEBUG port, place a shorting block on J2, Pin 2 and
Pin 3.
Note:
If supplying the 3.3 V supply from an off-board source via the J3 terminal block, do not place a shorting block on J2.
