D1
Link2 LPC43xx BOOT0_LED indicator. Reflects the state of
LPC43xx Link2 MCU P1_1. When the boot process fails,
D1 will toggle at a 1 Hz rate for 60 seconds. After 60
seconds, the LPC43xx is reset.
D2
Tri-color LED
– Driven by Target LPC54102 MCU. JP6
must be shunted for +3.3V to be applied to D2 anode. The
default shunt for JP6 is a 0Ω resistor installed at JS17.
D3
Target LPC54102 Power LED.
D4
Target LPC54102 Reset LED
– LED is on anytime the
Target RESETn is pulled low.
