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.
