2.6 Debug LEDs

Three on-board Light-Emitting Diodes, (LEDs), are provided to allow real-time
debugging for user programs. These LEDs will allow the programmer to monitor program
execution without having to stop the program during debugging; refer to
LED1 is controlled by Port B's PB0 signal. User LED2 is controlled by PB1. User LED3
is controlled by PB2. Setting PB0, PB1 or PB2 to a Logic One value will turn on the
associated LED.
