Power

The MiniProg3 requires a connection to the VDDIO supply of the target device to set the voltage
level used for communication. This is required regardless of the communication protocol and the
port selected. One of the connector's VTARG pins must be connected to the VDDIO supply of the
target device. For PSoC 3, PSoC 4, PSoC 5LP, and PSoC 6, this is the VDDIO1 supply because this
supply is used to drive the debug pins. If you do not connect the VTARG or you connect it to the
wrong supply, MiniProg3 cannot communicate with the target device.
On boards where there is a single power supply for the entire board, MiniProg3 can, in some cases,
supply power to the board. This supply is limited to approximately 200 mA, and is protected against
excess current draw. You can select 1.8 V, 2.5 V, 3.3 V, or 5 V for the power supply voltage. The 5-V
