User LED (D5) and C-Trig (Software Cursor)
The user LED (D5) and the software cursor trigger (C-trig) are available only for DA14531
FCGQFN24 PRO-DB. The user LED is enabled by default and it is driven from P0_9 of DA14531
FCGQFN24 PRO-DB (P1_0 of PRO_MB). The C-Trig is used by the power profiler of SmartSnippet
Toolbox to enable the software cursor. It is connected to P0_11 of DA14531 FCGQFN24 PRO-DB
through a 1 k
Ω resistor.
