Description

Section

JP1

Target processor selection for the on-board Debug Probe.

Jumper open (default) the LPC54S018J4M Target SWD interface
enabled. Normal operating mode where the Target SWD is
connected to either the on-board Link2 Debug Probe or an external
Debug Probe.

Jumper shunted, the LPC54S018J4M Target SWD interface is
disabled. Use this setting only when the on-board Link2 Debug
Probe is used to debug an off-board target MCU.

For On-board Target place in position 1-2 (default)

For Off-board Target place in position 2-3

JP3

This header (not installed by default) provides a convenient
connection point to provide external ADC positive and negative
voltages. To inject these voltages at this header SJ22 (for VREFN)
and/or SJ23 (for VREFP) need to be moved from the default 1-2
position to the 2-3 position.
