JumpersCircuit ref Description SectionJP1 Target processor selection for the on-board Debug Probe.Jumper open (default) the LPC54S018J4M Target SWD interfaceenabled. Normal operating mode where the Target SWD isconnected to either the on-board Link2 Debug Probe or an externalDebug Probe.Jumper shunted, the LPC54S018J4M Target SWD interface isdisabled. Use this setting only when the on-board Link2 DebugProbe is used to debug an off-board target MCU.3, 4JP2 Buffer Power SelectionFor On-board Target place in position 1-2 (default)For Off-board Target place in position 2-33, 4JP3 This header (not installed by default) provides a convenientconnection point to provide external ADC positive and negativevoltages. To inject these voltages at this header SJ22 (for VREFN)and/or SJ23 (for VREFP) need to be moved from the default 1-2position to the 2-3 position.SeeSchematic
