Jumpers
ULINK has only two sets of jumpers: Gnd and VCC.
ULINK Adapter - Jumpers (cover off)
The Gnd jumper (Txd/Gnd/Rxd) pins are currently unused. Do not install jumpers on these pins.
The VCC jumper determines the source of VCC power for the JTAG interface.
- If the target hardware provides VCC to the JTAG interface, set the jumper at VCC to the Ext. position.
- If the target hardware does not provide VCC to the JTAG interface, set the jumper at VCC to the 3.3V position.
