9. LEDs
There are 80 LEDs on the EasyARM v6 development system used to visually indicate the state of each microcontroller
I/O pin. An active LED indicates that a logic one (1) is present on the pin. In order to enable LEDs to illuminate, it is
necessary to select the appropriate port (PORT0, PORT1 or PORT2) by using DIP switch SW1. Port PORT3 is not
connected to LEDs.
