1.8 LEDs
Table 5 describes the FRDM-MCXN947 light-emitting diodes (LEDs) that correspond to the target MCU. The
board also has some MCU-Link-specific LEDs, which are described in Section 3.10. The LEDs are shown in
Figure 3.
Note: The FRDM-MCXN947 board also has three status indicator LEDs for MCU-Link. For details, see
Section 3.10.
Part
identifier
LED color LED name / function Description
D1 Red Reset LED Indicates system reset activity. When board reset is initiated,
for example, by pressing the SW1 reset button, the D1 LED
turns ON.
D2 Red/green/blue RGB LED User application LEDs. Each of these LEDs can be controlled
through a user application.
• Red LED connects to target MCU pin P0_10
• Green LED connects to target MCU pin P0_27
• Blue LED connects to target MCU pin P1_2
D5 Green P3V3 PWR ON Indicates P3V3 power on status. When P3V3 is available on
board, D5 turns ON.
