16.0. LEDs
There are 64 LEDs on the BIG8051 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, PORT2, PORT3, PORT4, PORT5, PORT6 or PORT7)
using DIP switch SW9.
