4.9.1 User LED (D5)

One user-programmable blue indicator LED (D5) is available on the WBZ451 Curiosity Board, and this LED can be turned ON or OFF using the connected GPIO pin PB7. Drive the pin to a high level to turn OFF the LED and drive the pin to a low level to turn ON the LED.

Important: PB7 is also SWO pin on the WBZ451PE module. During a programming/debug session with MPLABx IDE, this pin is always driven low from the WBZ451PE module, thus making the user LED turned ON during the entire DEBUG session. When the DEBUG session is exited, this pin operates normally.
