Solder the resistor on ICEJPR1 (MCUVCC) depends on the target chip operating voltage.2. Solder the resistor on ICEJPR2 (ICEVCC) depends on the ICE chip operating voltage.3. Switch the SW2 to OFF.4. Connect the external power supply to ICEJ3.Table 2-10 presents all power models when supplies external power through Nu-Link2-Me. The Nu-Link2-Me external power sources are highlighted in yellow.ModelTargetChipVoltageICEJ3ICEJPR1(MCUVCC)Selection [1]ICEJPR2(ICEVCC)Selection [2]ICEChipVoltageSW2Selection J2 Vin JP11 1.8 V Connectto PC 1.8 V 1.8 V 1.8 V Off Ignore Ignore 1.8 Voutput2 3.3 V Connectto PC 3.3 V (default) 3.3 V (default) 3.3 V Off Ignore Ignore 3.3 Voutput3 5 V Connectto PC 5V 3.3 V (default) 3.3 V Off Ignore Ignore 5 VoutputX: Unused.Note:1. 0 Ω should be soldered between ICEJPR1’s MCUVCC and 1.8 V / 3.3 V / 5 V.2. 0 Ω should be soldered between ICEJPR2’s ICEVCC and 1.8 V / 3.3 V.Table 2-10 Supply External Power through Nu-Link2-Me
