General Purpose LEDs
LED D2 is a general-purpose LED and it is driven by P0_9. LED D2 shares same configuration as
LED D5 of DA145xx DEVKT-P PRO-MB (D5 is driven by P1_0 of motherboard which is P0_9 of
DA14531). See Figure 15.
LED D1 is driven by P0_8 and it is not populated. User can mount a LED like D2.
General purpose LEDs circuitry is completed with Jumper header J5. J5 is optional and it isolates
signals P0_8 and P0_9 when LEDs function is not used, so signals can be directed to other
functions.
